    Hi tljay,

    If you absolutely want to, you can use the custom slot and enter your own OPUS command line.

    I picked mono for anything under 80k because it didn't sound good enough with stereo at that bit rate to my ears. Opus is an excellent codec but it is not as efficient as HE-AAC at low bit rates.

    Best,

    thats the question, what do i need to enter in this command?

    you can compare my streams

    opus 48kbps 48kHz stereo

    aacp 48kbps 44kHz stereo

    No codec exists yet that I will listen to at 48kbps other than for testing purposes.. not even aacPlus.
    But, I can listen to 64kbps aacPlus all day.

    BaOne opus command line:

    opusenc.exe –quiet –bitrate %bitrate%.000 –raw –raw-bits 16 –raw-rate %samplerate% –raw-chan 2 – –

    Those two dashes at the end mean stdin/stdout and are required.
