Compression of Music with the DCT, intended for use on embedded architectures. Music should be 16bit integer little endian, signed stereo audio
g++ -o SimpleDCT SimpleDCT.c
Where input.whatever is your audio file:
ffmpeg -i input.whatever -f s16le -acodec pcm_s16le input.raw
./SimpleDCT e input.raw compressed.raw
# Here you can use the compressed audio, "compressed.raw"
# To decompress it into "processed.wav":
./SimpleDCT d compressed.raw decompressed.raw
ffmpeg -f u16le -ar 22050 -ac 2 -i decompressed.raw processed.wav
