    Have just successfully extracted a PCM audio track from a BD disc. The format is this according to Mediainfo

    Code:
     
    General
    Complete name                            : D:\Temp\Audio_3_English.W64
    Format                                   : Wave64
    File size                                : 2.07 GiB
    Overall bit rate mode                    : Constant
    
    Audio
    ID                                       : 0
    Format                                   : PCM
    Format settings, Endianness              : Little
    Format settings, Sign                    : Signed
    Codec ID                                 : 00001000-0000-0100-8000-00AA00389B71
    Bit rate mode                            : Constant
    Bit rate                                 : 4 608 Kbps
    Channel(s)                               : 2 channels
    Channel positions                        : Front: L R
    Sampling rate                            : 96.0 KHz
    Bit depth                                : 24 bits
    Stream size                              : 1.00 Byte (0%)
    What I want is to convert that audio track onto a file I can burn an audio CD with.

    The problem is I can't open the file with Soundforge 8.0, so I wonder:

    1) If a later SF version would.

    2) If I should proceed in a different way to extract the audio track and/or convert it.

    You'll have to convert the sampling to 44.1 KHz, the bit depth to 16 bits and the bit rate to the normal 1500 or so Kbps that audio CD uses.

    Audacity can probably open it and convert it for you, but even at CD specs you may have more than will fit on one CD. I'm not sure. Just be prepared that this can happen.

    Oh, yes, I'm aware that I will have to downgrade all that you mention (sampling, bit depth, bit rate).

    Will see how can I edit it so it fits in one CD, if possible. If not I will put it on two.

    Audacity has editing features and it's free. Maybe it can do everything you want.

    eac3to should be able to convert W64 to WAV as well.

    If you choose a REAL audio editor anyway,
    make sure it uses proper dithering when converting from 24-bits to 16-bits.

    Yes, Audacity did the conversion. Thanks.

    I converted the file to one I could open with Soundforge, which I'm more familiar with. What's the bit rate for a CD? I still have 3072 kbps.

    Audacity did the bit conversion to 16.

    I have some issues with eac3to, but due to some incapacity of mine to use it. I need some proper how to instructions.

    1411.2kbps <== 2 channels, 44.1kHz, 16-bits.

  8. What about just using foobar2000 to do it?

    After downconverting, you shouldn't have any trouble getting the single file to fit onto a single CD: it's only ~62.5minutes, according to my calculation.

    Should be able to just create a CUE file from within ImgBurn (using the downconverted WAV file). You could even add index points (aka "chapter" markers). Then burn away!
