Record PCM Through NetMD

You can send raw PCM data in a WAV-container to the NetMD by default encoded in ATRAC (SP) on the device using the chip on the unit.

If you own a one of the units tested positive below you can use the -d lp2 or -d lp4 flag to save the PCM as ATRAC3 on the disc.

Brand	Type	LP2/LP4
Sharp	IM-DR410	✅
Sharp	IM-DR420	✅
Sony	MDS-JB980	✅
Sony	MDS-JE780	✅
Sony	MZ-N710	❌
Sony	MZ-N510	❌
Sony	MZ-RH910	❌
Sony	MZ-NH600	❌

The list is not yet complete, so if your device is not listed and if you hear only silence after the transfer was completed you device does not support ATRAC3 through NetMD (USB). You could always use the solution mentioned below to encode the PCM to ATRAC3 first before transfer.

In each case you will need to prepare your source (mp3, aac, flac etc.) the WAV yourself like so:

ffmpeg -i mytrack.flac -f wav -ar 44100 -ac 2 mytrack.wav
netmd-cli send mytrack.wav

It's recommended to use ffmpeg.

Use LP2 Without NetMD Encoding Support

You will need to create the LP2 files yourself on the host machine. For this you can use atracdenc created by Daniil Cherednik and put the LP2 encoded track into a WAV-container.

example

First convert your mp3, flac etc. into a stereo wav file:

ffmpeg -i mytrack.flac -f wav -ar 44100 -ac 2 out.wav

Now encode the wav into an ATRAC3 file with a bitrate of 128 for LP2:

atracdenc -e atrac3 -i out.wav -o out.aea --bitrate 128

Put the AEA file into a WAV container like so:

ffmpeg -i out.aea -f wav -c:a copy mytrack_lp2.wav

And send the wav to the NetMD:
