This project does nothing. All the test sounds are inside. This is a project that has imported WAV files of different formats.
List of formats that work correctly: Unsigned 8 bit PCM Signed 16 bit PCM Signed 24 bit PCM 32 bit floating point 64 bit floating point U-Law A-Law IMA ADPCM (Mono audio only) List of formats that don't work correctly: Signed 32 bit PCM (silence) Stereo IMA ADPCM (very loud) Microsoft ADPCM (very loud) GSM 6.10 (noise) 32kbs G721 ADPCM (nothing) NIST Sphere WAV files leave a blank sound There are more formats out there, but these were all the formats that were in Audacity at the time this was made.
