7.7.1 Checklist for audio file function
Use this checklist to ensure the audio file will work:
1. Audio files are stored in the following SD card directory tree:
– '<flashdisk:>\PACE-Net\Wave\SSounds'
2. The audio format is 16 bit/48 kHz/mono.
3. The audio file is not compressed and is in 'Raw PCM' format.
4. Check the compression level.
– Open the file properties > 'File Information' tab > 'Bitrate' field.
– The value must be 768 kbit/s.
5. Normalize the amplitude to -12 dB 'full scale'.
6. Special 'chunks' in the '*.wav' file are not allowed and the 'DATA_CHUNK' must
be in the first 512-byte block in the '*.wav' file.
7. The file name is numbered '001.wav'…'255.wav'.
● Software for editing audio files may insert a 4 kB 'PAD chunk' or other 'chunks'
into the file before the 'DATA_CHUNK'.
● This is not supported by the devices, but 'PACE-Design' converts or removes
such chunks.
● 'RIFF INFO chunks' are fully supported by 'PACE-Design' for the purpose of
storing project-dependent metadata in the '*.wav' audio file of the devices.
● You will find information on writing files to the microSD card with 'PACE-
Design' in chapter 'Write SD-Cards [➙ 189]'.
● You will find information on supported metadata in chapter 'Injected Sound
[➙ 147]'.
