    Sample Rate Conversion - which option is best? And am I getting it right?

    Hi all

    I've got a few 320 CBR mp3s which are 48kHz and I want to convert them to 44.1kHz.

    Is this the way to do it... Right click the file, choose Convert to, then in the convert dialogue choose the same format as the original with the same options as the original (i.e. mp3 CBR 320). If doing so, does that mean the converter will still convert from mp3 to mp3? Or will to recognise that it is being asked to convert to the same and therefore ignore the file format part?

    As for the sample rate conversion itself, I see two options...

    1. On the mp3 encoder there is an Advanced button, and within there is a drop down menu for Frequency. It is currently defaulted to "[as source]". But there is an option here to choose 44.1.

    2. Or should I leave the above on "[as source]" and instead use the Resample dsp?

    Many thanks

    Using Resample DSP is best, however to reencode mp3 it is first decoded, then encoded.

      Thanks for explaining. Is there a way to do it with the decode/recode? Can I just resample and nothing else, and if so how please?

      Many thanks

        It is not possible.

          OK, thanks for confirming. Presumably the decode/recode doesn't have too much of a detrimental effect on the sound quality of the file? Or does it?

            At high bitrates it will not.
