["Jurgen." <invictaz@yahoo.com>]

Does this mean I can download .wav to my MZ-RH1 in PCM (44.1 khz)?

Or is this only for NetMD?

Hi,

i made some changes to libnetmd and netmdcli to support download of
audio files in pcm format (filename: *.wav, codec: pcm, 16 bit, 4100 Hz,
stereo).
Codec used on the minidisc is Atrac SP stereo, but this can be changed
anytime if wanted.

I fixed a bug in my patch, i changed the byte order conversion loop
since my first try but forgot to change loop condition _expression_.
Apply this patch to my last one.

You can not change the codec on the minidisc. While you are able to send
a command to the NetMD device that tells the recorder that you are going
to send uncompressed PCM and want to write a LP2/LP4 track, that command
gets rejected. The only valid combinations are
PCM -> SP
LP2 -> LP2
LP4 -> LP4
I don't remember whether PCM -> SP Mono support is consistently
implemented in all NetMD devices.

If you would like to have LP2 or LP4 on the disc, you need to encode it
before downloading.

This is not correct, i tried many combinations and all commands gets
accepted.
O.K., the tracklist shows incorrect length and the audio data is
corrupt, but download works.
Tested with MZ-RH1 and MZ-NH1.

But, of course, you are right, we should avoid incompatible combinations
because of corrupt data on the disc.
