Mp3Doctor PRO showed that the gain to an mp3 needs to be calculated at every moment, processing, maximizing and optimizing each frame. With modern audio devices, it is not just a problem of volume levels too high or too low at the beginning of each song. Today, with the quality of sound reproduction devices that exist, the option Mp3Gain offered is totally inadequate and has been largely overcome. Mp3Gain? Well, I would say that Mp3Gain was an acceptable solution (just acceptable), some years ago. I must confess that I had never heard the clarity and separation of musical instruments and environments, until I buy Mp3Doctor PRO and process my entire music collection. I am an amateur expert on everything that has to do with the quality of audio and Mp3Doctor PRO has left me really impressed.įor 30 years I have been collecting a large number of albums by artists such as Abba, Pink Floyd, etc. #Clipping mp3 gain portable" Mp3Doctor PRO, unlike Mp3Gain, was especially designed for modern audio equipment, to use with laptop computers, portable mp3 players, headphones, speakers and other modern audio devices. In these times when listening to modern music using these devices and audio in noisy environments (in the office, in the car on the street, etc), the subject of mp3gain must be resolved so that the user listen to a sound track in the car or a portable audio player, can really listen and enjoy all parts of the song properly. One approach that has not been sufficiently analyzed when developing tools based on peak volume was the fact that you listen to your mp3s using modern sound equipment, such as mp3 players, computers, etc. The so-called gain of an mp3 is quite complex and to be properly analyzed, must be effected with an appropriate method. This technique called "peak-volume gain" is just a simple arithmetic operation, which offers obvious too simple and therefore unsatisfactory.Īll experts agree that the peak level indicator is a totally inadequate and inappropriate method to measure and manipulate the perception of loudness of an audio track. Under this procedure what happens is simply seeking the highest peak of each mp3 and compared with the highest peak possible, then all is mp3 amplified, multiplied by the highest possible value of that peak. 89dB seems to be pretty much "written in stone".There is a misconception about getting a proper normalization of volume using the outdated method of standardization based on peak volume of each track. If I was using a higher target volume though, I'd probably consider enabling the "don't clip" option as no doubt there'd be a lot more MP3s which would need to have their volume reduced a little more to prevent clipping, which of course would mean they're not all being adjusted to the same target volume any more (93dB or whatever you're using), which might defeat the purpose a little.įor the record, I'm not aware of any other programs which let you adjust the target ReplayGain volume as MP3Gain does. I don't use that option as with a target volume of 89dB it's only the occasional MP3 which has levels above 0dB (which might cause clipping) so I just leave them at 89dB. If I remember correctly there's an option called "don't clip when applying track gain" or something similar, and with it enabled MP3Gain will adjust the level to achieve the desired volume and if need be it'll reduce it some more to prevent clipping (do you see lots of red "Y"s after running an analysis?) Part of my reason for doing so is it leaves enough headoom for most MP3s not to cause "clipping" after ReplayGain has been applied.
