    Default Audio Bitrate

    I'm recording video with webcam and it creates one flv file and one transcoded .mp4. When I record a video from webcam, I want to change audio rate. I want to make it 48Khz but audio codec is AAC Mono 16Khz in both files.

    My AS3 code:

    microphone.rate = 44;
    microphone.codec = SoundCodec.SPEEX;
    microphone.setSilenceLevel(0);
    microphone.setUseEchoSuppression(true);


    My transcode.xml:
    <Audio>
    <!-- AAC, PassThru, Disable -->
    <Codec>AAC</Codec>
    <Bitrate>48000</Bitrate>
    <Parameters></Parameters>
    </Audio>

    Can you suggest a solution for it please? Maybe I don't need 48000Khz audio but I want to know if changing audio rate is possible or not.

    Thanks a lot

    Default

    I don't see a way to change the sample rate (Hz) in the default template or extended parameters. And I don't think you can increase sample rate from 16 to 48 in any case.

    You should probably reset /Bitrate to "${SourceAudioBitrate}"
