convert *.AOB files

[Dimon911]

Hi,

I found in my files some old *.ISO  I tried to play it with enabled decoder with AIMP, no chance.

So I mounted it, it is an DVD with no video but with audio files inside of AUDIO_TS folder, those files have *.AOB format (Video on DVD has *.VOB).

There is no decoder for AIMP that can decode this files. The files are ~1GB large typical for DVD. I can play it with MPC.

Inside of those *.AOB's is an direct PCM (PCM_dvda) Stream with 6Ch 24bit 48kHz according to LAV Audio Decoder (0.83.0.1 -git) info

If I disable  .*lpcm or *.pcm formats of LAV  it switches from external to internal (of MPC) filter type. So this change has an impact. BUT!

Rather pcm or lpcm are supported by AIMP, at least my search give no results.

Also I tried to rename the file endings to possible pcm alternative, no success.

My final goal is to transform from this strange format to multichannel FLAC.
Thanks

AIMP cannot play this. Only SACD and Data ISO supported
