Korg Volca Sample uploader for linux.
Place the samples you want to upload in an empty directory.
Connect the audio out of your machine to the audio in on the Volca Sample at high volume. Make sure no other application which might produce sound is running.
Pass the full path to the directory as an argument to gnuvolca.
WARNING: Do not execute the script without pluging the line out to your volca. Reproducing the raw audio through your speakers might damage them.
$ ./gnuvolca.py --dir /path/to/sample/packThe Korg Volca Sample has a memory of 2 MB, so the total size of all samples
cannot exceed this hardware limit. See Preprocessing for how to change
the sample rate to reduce the individual file sizes.
The Korg Volca Sample supports 16-bit depth signed-integer encoding for the
wav files. See Preprocessing for how to change the file encoding.
To both ensure correct encoding, and change the samplerate of the samples to 4000 Hz, run the following shell script from the directory containing the samples (requires sox):
for file in *.wav; do
sox "$file" -e signed-integer -b 16 "resampled/${file%.wav}_resampled.wav" rate 4000;
