Creating simulation files
Simulation files are raw (header-less) binary files with 16-bit signed integer samples recorded at 51200
Hz. You can create new simulation files using an audio editor.
In the following instructions we will make a 440 Hz sine tone using the free audio editing
software
. Adjust default sample rate and sample format:
Edit > Preferences > Quality
. Set
the default sample rate to
51200 Hz
and sample format to
16-bit.
Create a 440 Hz, 30 seconds long sine tone:
Generate > Tone
.
Export file as raw file (header-less) 16-bit signed integer samples:
File > Export > Other uncompressed
files
. Set header to
RAW
and encoding to
signed 16-bit PCM
