This should reduce the problem that some sounds are very silent and some are loud.

To keep sounds consistent a sound file should follow the parameters listed below.

Format

Internally qTox needs PCM with signed 16Bit integers and a samplerate of 48kHz and one channel (mono).

You can use ffmpeg to create those files as follows:

ffmpeg -i notification.wav -f s16le -acodec pcm_s16le -ac 1 -ar 48000 notification.s16le.pcm

Normalization

All sound files should have their maximum at -1.0 dB. To normalize them correctly you can use Audacity with the "Normalize" plugin.
