About this aac to wav converter
AAC is the compressed codec inside M4A and most streaming and YouTube audio, here as a raw .aac file. WAV is uncompressed PCM audio: large files, no quality loss, and accepted by every editor and DAW. The conversion runs in your browser with ffmpeg compiled to WebAssembly, so the file never leaves your device and there is no size limit beyond your memory. WAV is lossless, so the result sounds exactly like the AAC, no better: quality lost when the AAC was made cannot come back. Use WAV when an editor or device needs it.
