Uncompressed 16-bit PCM in a .wav file. Choose 44.1 or 48 kHz; the source keeps its mono or stereo channel count. This converter does not offer 24-bit, 32-bit float, or multichannel output.
It will not recover detail already lost in an AAC recording. WAV changes the output format. Resampling and conversion to 16-bit can also change the samples, so keep the original if you need it for future work.
This tool writes uncompressed PCM audio. Its size depends on duration, sample rate, and channel count. A larger output does not prove better sound.
