Increase Volume
Since, decades ago, the file exchange started on the internet, it was necessary to look for ways to make the volume of the different audio files sound the same. The first reaction of joy for being able to exchange song archives was overshadowed by the shock of discovering that the volume levels were very different.
Sound Normalizer – Volume Equalizer
Then the word “normalizer” arose by all praise. They dedicated themselves to thinking how to achieve that the sound had a similar loudness level. The first attempts were somewhat innocent, as for example, simply mediros the peaks of maximum volume of each song and see if some could be amplified without reaching the distortion.
mp3 louder – Volume Level
Obviously at first this search was only devoted to trying to match the sonority of the mp3s. First, because at the beginning there were no other good quality coding formats. It sounded to everyone that an mp3 retained the same quality as the original wav if they maintained a samplerate and bitrate high enough.
How volume booster works
As we explained initially, the first attempts were timid and naive, but little by little they were professionalized. Becoming more efficient, at least for the quality parameters in force at that time.
Although our mind keeps inteacts the results obtained by the legendary Mp3Gain, today would not be enough or satisfactory for current devices.
Currently there is a lot of hardware, usually quite expensive, such as compressors, which manage to avoid spikes and, on the other hand, boost the audio volume of a singer’s bass (for example) so that it is perfectly audible, more or less at the same time. level than a scream.
This hardware is used in radio stations or stadiums where concerts are held before thousands of attendees, and where it is the job of the mixing engineer, that everything is audible to the public. Where the different volumes do not silence quieter things. For example, the rumble of the drums or an electric guitar does not cover a voice singing at low volume, everything is audible.
These achievements are very sophisticated and usually require very expensive equipment. The software called Mp4Gain has identical results at a really low cost. In fact many radio and television stations, as well as audio producers, and even universities, use Mp4Gain to obtain results very similar to the one described.
