The usefulness of an mp3 normalizer

The usefulness of an mp3 normalizer…  not only a mp3 volume increaser

The usefulness of an mp3 normalizer is not only amplify every song completely until they have similar volume levels, that is something that has already been exceeded. The advanced algorithm Mp3Doctor PRO makes a much more complex task: analyzing the internal volume levels of each song, every millisecond.

Forty thousand times per second, in most cases and tries to soften, if necessary, or increase, if necessary, the volume at each instant. For this reason, the term Volume Booster is inaccurate, because to do more to boost volume is adjusted, it evens out. So Volume Leveler is more accurate.

To standardize the quality, volume, and the sensation produced by each of the mp3 files from your collection, you need to process your mp3s with Mp3Doctor PRO.

The equalize function, treats each track sound so unique, and not just adjusting and normalizing elvolumen, but the ‘coloring’ or ‘texture’ (to put it in some way) of some songs in particular. So if a track sounds old ‘opaque’, Mp3Doctor not only normalize the volume, but will return the luster.

Finally, to keep in good condition a collection of mp3s, Mp3Doctor PRO is a tool that not only is useful to normalize, but also to trim, change the tempo, equalize, etc. We recommend you download the software and test it on your own computer.

Mp3 Equalize, Compression, Limit & Expand – Mp3 Normalizer



MPEG-1 Audio Layer III or MPEG-2 Audio Layer III, more commonly known as MP3 is an audio compression format that uses a proprietary digital algorithm to achieve loss smaller file size. It is a common audio format used for music both on computers and portable audio players.

MP3 was developed by the Moving Picture Experts Group (MPEG) to be part of the MPEG-1 and later and more extended MPEG-2. Created using an MP3 compression 128kbit / s have a size of approximately 11 times lower than its namesake in CD. An MP3 can also be compressed using a higher or lower bit rate per second, resulting directly in their degree of end audio quality, and in the resulting file size.

The Mp3 psychoacoustic model

Compression is based on reducing the dynamic range irrelevant, ie in the inability of the auditory system for detecting quantization errors in terms of masking. This standard divides the signal into frequency bands that approximate the critical bands, then quantified each subband based on the detection threshold of the noise in that band. The psychoacoustic model is a modification of the employee in Scheme II, and uses a method called polynomial prediction. Analyzes the audio signal and calculates the amount of noise which can be introduced depending on the frequency, ie, calculates the “amount of masking” or masking threshold as a function of frequency. The encoder uses this information to decide how best to spend the available bits. This standard provides two psychoacoustic models of different complexity: model I is less complex than the psychoacoustic model II and greatly simplifies the calculations. Studies show that the distortion generated is imperceptible to the ear experienced in an optimal environment from the 192 kbps and under normal conditions [citation needed]. To the inexperienced ear, or common, with 128 kbps or 96 kbps up enough to be heard “good” (unless it has a high audio quality where it shows too serious lack of sound and highlights the of “frying” in the treble). In people who listen to much music or have experience in the hearing, from 192 or 256 kbps is enough to hear well [citation needed]. The music circulating on the Internet, mostly, is encoded between 128 and 192 kbps.

The Mp3 psychoacoustic model

Mp3 file is made up of different MP3 frames which in turn are composed of a header and data Mp3 MP3. This data stream is the “elementary stream”. Each of the frames are independent, ie, a person can cut the frame of an MP3 file and then play on any MP3 player market. The header consists of a synchronizing word which is used to indicate the beginning of a valid frame. Following are a series of bits that indicate that the scanned file is a file and if using Standard MPEG Layer 3 or not. After all this, the values ??differ depending on the MP3 file. Value ranges are defined in ISO / IEC 11172-3.

Volume Level

The amplified sound is the process of increasing its amplitude, which also drives up the intensity (loudness) and power (volume). Amplification does not act directly on the sound wave, but acts on the electrical signal that has been transformed (transduction), prior to entering the electronic equipment for processing. At the exit of (preamplifier or an amplifier), when the signal is again converted into audio, this change (gain) will affect the resulting waveform, which will increase its amplitude and will, therefore, more intense and potent.

Digital Audio

The 80’s frame an event in audio history: the arrival on the scene of the compact disc, or CD, and since then could not use more technical groove width, being the 16bit a hard limit. Thus, the competence of the studios had to be limited, such as radio, electronic weapons, so of course, the multiband processor soon join the arsenal of mastering studios. This cyclic process is returned. Radio stations compete for the volume, but at the same time trying to achieve a homogeneous throughout its volume content while that content producers also compete for the volume, thus hindering the initial purpose. The war is perpetuated because the volume is fed, because there comes a time in history that is no longer producing music but only to sell more albums than others, forcing them to compete with all available weapons volume being one of the most used, even though his method is as effective as currently questioned.




1, Equalize: With equalization the aim is to adjust the tonal characteristics of audio to be processed, either to mitigate or accentuate it. It is very common when mastering EQ make major changes unless necessary to maintain the equalization is usually carried out earlier in the mixture, usually small adjustments.

2 ° Compression: The use of a compressor or limiter when carrying out the mastering is intended that no strong differences between the parties of more force and less force, thus achieving a certain stability.

3  ° Limit: While a compressor compresses the signal is above the threshold that you will point out, the limiter does is cut the signal, ie, while a compression function is applied in a 3:1 ratio limiter is applied infinite ratio: 1.

4 ° Expand: An expander is the inverse function of a compressor. It is widely used for audio restoration and the information that is stored on tape and that because of time and other factors is damaging information that is stored in them, it is also used to reduce background noise that is unwanted into professional recordings.It is true that both in some cases and in others it is necessary to do this, but still in this process nor is there mandatory guidelines is a question always of the intentions of the musician or technician mastering style that will be mastering and in many cases is a matter of fashion. For example, today is carried out fashion war of the volume in which what is sought is a extreme compression and maximization, this has the razomiento is that the human ear acts differently depending on the level of SPL and the higher the greater the number of high and low frequencies that we perceive. It also has much to do with the listener’s attention, for example, someone takes half an hour listening to the radio to a certain level and, suddenly, the radio plays a song that has a much higher level, automatically the listener pay attention. When performing this process should take into account that also has negative factors such as loss of dynamic and it can end up being tiring to the ear, in fact has many detractors as Geoff Emerick (known for his work with The Beatles from Revolver to Abbey Road), Steve Hoffman, and many others, including music lovers and fans of high quality as Bob Dylan said:Listen to these modern recordings are atrocious, they have sound everywhere. There is no definition of nothing, no voices, no nothing, all static.Bob DylanWhat we must never fall into error is to think that mastering can fix all the problems that have accumulated over recording, editing and mixing. The role of Bob Katz mastering as said is:Mastering is the art of compromise, to know what is possible and the impossible, and make decisions about what is most important in music.

Mp3Gain PRO -User review

I am making custom boot animations for android OS based phones, and some of the audio files I use are not loud enough. I need to increase their overall volume by 10% to 20%. I did a search on google and found your software/site. It works so perfectly I felt I should pay for it to show my support for good software (yours). Thank you and I greatly appreciate it!

I used Mp3gain a long time ago,  just got a new pc and lost the old program in the process.. Went onto the internet and found your product did a download tested it out, pleased with the results..


I recieved the info on your product from my brother. He said he loved it so I thought I would give it a try.
I have used MP3Gain for some years, on&off, and was looking for 
something new and stumbled on SuperMP3Normalizer.
While reading I found that MP3Doctor PRO did that and more so I decided to 
buy MP3Doctor PRO.

Some reviews and feed back from customers

I asked a friend of mine about “how to ‘level’ the volumes for MP3, and he told me he used to use “MP3GAIN” on his Mac several years ago … I tried to download the free PC version, and it wouldn’t work … that MP3GAIN on included a link to check out “MP3GAIN PRO” and stated that it was a separate program.

Well, I needed to get my MP3s leveled, so I tried the free sample and it worked AMAZINGLY WELL … so well that I have no qualms about paying $25 for the program.  Thank you so much, this is just what I needed!
Ryan E.

    I found out about your software 2 ways; word of mouth and online.   I asked a friend about how to adjust the volumes of my mp3 flies and he suggested your software and when I researched this I also read the reviews of your software.
Hi……I discovered this software on “Google” when I was searching for a way to equalize the volume on my collection of MP3 files…
Works Great…..Thanks…will be sure to spread the word….
I just did a google search for “.wav to .mp3″  Very nice application,
by the way.  The normalizer is a great tool.

I found MP3Doctor PRO simply looking up an easier way to normalize songs without having to open up an audio software. 🙂 Thank you!

MP3 Doctor PRO is een editing tool waarmee je optimaliseren, testen, aanpassen en verbeteren van al uw MP3’s en Wavs op verschillende manieren. U kunt repareren onvolmaakte songs of te wijzigen met TRIM, vereffenen, resample, en met een zeer efficiënte en verbeterde procedure voor normalisatie MP3s – VOLUME normaliseringsinstelling en volume boost – functie. Het doel is u in staat om een vergelijkbare kwaliteit, volume en geluid in al uw MP3’s en ontdek een nieuwe kwaliteit in uw mp3-bestanden.

Door deze manier zul je niet alleen maar een consistent volume in uw verzameling MP3’s, maar u ontvangt ook een constante kwaliteit.

In de toekomst, bij het spelen van uw afspeellijst op uw mp3-speler, uw mp3-bestanden goed in overeenstemming met een passende omvang.

Er worden geen bestanden die klinkt ‘opaque’, ‘versleten’, ‘saai’ of ‘zwak’, en met een laag volume. Ook anderen die geluiden te sterk, schandalig of luid. Het afspelen wordt glad, met een goed volume, zo nodig om een onderscheid te maken en te genieten van elk nummer en voor elk deel.



Audio normaalgloeien is het proces van toenemende (of dalende) de amplitude van een audio-signaal, zodat het resultaat overeenkomt met een gewenste maximale amplitude. Gewoonlijk wordt de normalisering verhoogt de amplitude van de audio golfvorm met een maximum niveau dat geen enkele verdere verstoring. Zei in gewone woorden, normaalgloeien versterkt het volume (winst, volume) aan de maximaal mogelijke.

Het concept van dynamische normaalgloeien wordt gebruikt op dit moment, wat betekent dat het volume wordt vergroot in elk frame, door middel van ingewikkelde berekeningen, in plaats van het uitvoeren van een totale versterking van het audiobestand.

De dynamische normalisatie is de meest efficiënte methode te versterken, zodat een doeltreffende en wereldwijd, een audio-bestand (WAV, MP3, etc).

Het verschil tussen de dynamische normaalgloeien enerzijds en de oude methode bekend als mp3gain aan de andere kant, is in feite dat de toename van het volume plaatsvindt in elk frame van het archief, zelfs rekening houdend met verschillende geluidsdragers, zoals hoge frequenties, hoge en bas. Er is een totale winst, gebaseerd op een complexe berekening die alleen vullen de audio niveau dat nodig is om nadere uitwerking.


Waarom wil iedereen hard te normaliseren hun verzameling van mp3-bestanden?


Jaren geleden, mensen geluisterd naar hun vinyl lang speelt placidly vergadering in de woonkamer, omgeven door een vriendelijke stilte.
Zelfs de covers van de oude grammofoonplaten werden groter en bevatten veel informatie, songteksten en vele foto’s. Mensen kunnen comfortabel zitten, zonder enige haast om te luisteren naar elk LP (Long Play).

Het geluidsniveau laag was in die omgeving en de mensen kunnen horen elke noot en elk geluid detail opgenomen in de LP.

Maar vandaag, we horen onze favoriete muziek reizen in een trein, het rijden door een onderzeese tunnel, die in een park vol met andere sporters, enz.. De ruis is aanwezig om ons heen.

Ook moeten we beseffen dat we onze eisen voor kwaliteit en standaardisering van de omvang, wij zijn gewend om met spelers die een betere geluidskwaliteit. Vandaag hebben we een norm voor een kwaliteit die veel hoger is dan de norm die bestonden op het moment van dit geïdealiseerd scène die we al eerder zagen: een persoon zit rustig in huis, genieten van de muziek op een vinyl LP, terwijl u op de cover van de LP.

Om muziek af te spelen in de moderne hoogwaardige apparaten die momenteel bestaan, moeten we “tweaken” die oude opnamen van geluid, het versterken van de lage, midden en hoge tonen.

Momenteel is het niet genoeg om de nummer een, met een totale toename in volume. Onze hoge normen vereisen een moderne en efficiënte proces van normalisatie van het volume. Dus moeten we versterken en verwerken elk frame onafhankelijk. De verhoging van de lage frequenties waar nodig, bevestiging van de hoge noten soms verduidelijken en benadrukken de stem in een nummer … Kortom, we hebben een proces van normalisatie in overeenstemming met de hoge kwaliteit muziek afspelen apparaten die we gebruiken vandaag.

Evenmin mogen we niet vergeten de rumoerige omgeving waarin wij leven in onszelf.


Bass Boost


Mp3Doctor PRO kan versterking van de bas, verrijking van de ervaring van het luisteren ritme, Latin, jazz, salsa, rock en dance muziek, onder andere genres.

Misschien is het woord dat het best beschrijft dit proces is geoptimaliseerd normaliseren.

mp3 normalizer - mp3gain

Mp3Doctor PRO vergroot de ritmische en percussieve (drums) delen, verhoogt het volume krijgen in de bas, de middelste frequenties zijn geretoucheerd om de “aanwezigheid” van de stemmen en om de definitie van de instrumenten, zoals piano’s, gitaren, violen. Een van de opvallendste voordelen is dat je duidelijk kan waarnemen elk van deze muziekinstrumenten die zijn toegenomen en gedefinieerd; niet langer klinkende randen, vervormd of verward.
De hogere noten van het lied zal ‘glans op haar eigen’ na de normalisatie.

Wat zijn de methoden die we gebruikt voor de nadere uitwerking, gelijk en optimaliseren met verschillende niveaus van de verschillende instrumenten van elke song? Een zeer moderne normaalgloeien algoritme, dat zijn meestal gedaan beeld voor beeld (44100 per seconde gemiddelde).

Het resultaat zal zijn, zodat u niet nog meer te bewegen de volumeregelaar op uw mp3-speler met elke song afgespeeld.

Het zal je niet meer te voortdurend aanpassen van het volume schuifje bij het afspelen van MP3’s. U hoort instrumenten die nog niet eerder opgevallen.

Elke song zal in combinatie met het einde van het vorige nummer in een vlotte en perfecte manier.

Ook kunt u het tempo of de toonhoogte als je wilt een professionele DJ. Variaties in de hoeveelheid winst zal geen pijn.

Als een nummer begint met een zachte, lage volume, dit deel zal het volume adequaat zonder dat daardoor verstorend anderen delen die al een hogere of voldoende volume. Elk onderdeel van elke song zal heel hoorbaar, met de juiste volume.

Audio normalization Mp3 dynamic range compression

Audio normalization is the process of uniformly increasing (or decreasing) the amplitude of an entire audio signal so that the resulting peak amplitude matches a desired target (the norm).

Normalization is often used when remastering audio tapes for CD production, in order to maximize the signal level while not changing the signal to noise ratio. It is often combined with dynamic range compression and hard limiting to increase the apparent volume of a CD. It is typically applied along with other audio and digital processing, such as dithering.

Dynamic range compression, also called DRC (often seen in DVD and car CD player settings) or simply compression, is a process that reduces the dynamic range of an audio signal, that is, narrows the difference between high and low audio levels or volumes. Compression is commonly used during sound recording, live sound reinforcement, and broadcasting.

In simple terms, a compressor is an automatic volume control. Using downward compression, loud sounds over a certain threshold are reduced in level while quiet sounds remain untreated.

Sounds much fancy? Well, try Mp3Doctor PRO and you will get the same quality with just one click.

Is there a way to increase the volume of an mp3 file, other than turning the knob on the speaker or moving the slide up on the icon by the clock in the tray?
I have tried converting the mp3 file to a wave file & opening it in Talk Works Editor & then increasing the volume there, but it was not really successful as the gain was very little.
If I make an mp3 playlist of various files, when the mp3 player gets to some of the files, I have to increase the volume.
What I want to do, is to increase the volume of the file somehow, (using a program, I suppose), so that when the particular file is reached in the playlist, I don’t have to physically increase the volume.
It’s not unusual that audio files have different volume level. Some are too loud, others are just too quiet. You may want to increase volume of your records in several cases. For example, if you join two or more files together, it is better when they have approximately the same level. Another example, the audio can be so quiet that you aren’t able to hear it with your iPod or some MP3 player in a noisy place.

So, is it possible to deal with that?

Is there any freeware that allows you to increase the volume of an mp3 by outputting a new file? I have a few songs that are recorded at a low volume, and it is annoying when I have them in a playlist with songs that have a higher volume.


If you have a large number of mp3 files that are suffering from low volumes and wonder how you can increase the volume of each file easily, you should take a look at Mp3Doctor PRO. This mp3 volume adjuster can help you to increase mp3 volume easily. If you have trouble doing so when using other complicated mp3 editors possibly due to their tons of advanced features, then you should try it, its so easy to use (usually need just one click to do the job for you).
