As the name implies, this program removes silence from the beginning of a WAV or FLAC file. I wrote this tool since I had tons of batch-recorded samples from synthesizers which had a fixed amount of silence at the beginning.
I wrote this tool in about an hour or two, so don't expect brilliant code. Getting the job done was more important than beautiful code. For example, using FILE* instead of std::ifstream was simply done so that I could just feed the file directly into libflac.
SilenceRemove input_file delay [forced sample rate]
input_file: Filename of one FLAC or WAV file to trimdelay: Duration of silence to remove, in milliseconds (may be fractional)forced sample rate: Optional. Enforced a given sample rate for the delay to samples conversion.
- Little-Endian processors
- Visual Studio 2010
- Windows (widechar APIs are used)
- PCM and Float WAV samples, as long as they don't use WAVEFORMATEXTENSIBLE.
- FLAC samples
- Loop points in WAV format, and FLAC with embedded WAV loop points
It's advised to use this tool together with a batch file to run it over an entire directory of files. Example:
REM parameters: directory, delay
cd "%1"
for /R %%F in (*.wav, *.flac) do (
"path/to/SilenceRemover.exe" "%%F" %2
if errorlevel 1 (
echo FAIL
) else (
echo %%F
)
)
pause

I am not responsible if this tool sets your samples on fire. I tried it with a certain number of FLAC and WAV samples, but they all were created the same way with the same tools, so broken samples might screw up entirely (e.g. old 8-bit mono samples with an odd length that were saved with very old versions of OpenMPT, as it didn't write the required padding byte). Just in case, you should keep the original samples around in case the tool screws up or if you chop off too much silence. How about modifying that example batch file above to automatically create a backup? ;)
