Software amplification for choir practice files

[herbert]

Hi Tim

You cannot make up for limitations of a computer’s audio by changing the midi file or .wav file. The maximum you can have is 0dB. Attempting to go beyond that point will only give you distorted sound. Depending on the content, the max level may be less than 0dB for distortion-free operation. If you use GM midi, you can use velocity and channel volume to change the volume level of an instrument. To make sure that you have not gone into distortion, aim at a maximum level of -3dB. You can measure and adjust the wav file with an audio editor. I am using GoldWave. There are many free audio editors available on the internet. If your signal level is too high, you must record your music again at a lower level. Once you have optimised your .wav file for level, that is it. The only way to increase your volume is to use an external amplifier.

Best Wishes,

Herbert
