    Process of Replay Gain on Mac

    I need to tag my music with Replay Gain. I`m on a Mac and want to apply the effect on the iTunes Media folder. When I start the batch processing and I convert to "Replay Gain" - are the files encoded/decoded (what could make the sound quality worse)? Or does DBPA just "tag" the files like with this utility codecs that just run on Windows?

    As you seem aware, in terms of digital audio, the ReplayGain utility codec for Windows is non-destructive and just calculates and writes the ReplayGain tags.

    I assume the utility codec available on the mac is the same, but as I do not use the mac version, I cannot be sure.

    Why not copy an album in your iTunes library, to a location separate to the iTunes library and test the process yourself?

    ... I have just realised that you are double posting, very annoying!!

      I won`t hear a difference (I think nobody would hear this difference with high-quality-files). But if there`s a quality loss, it would be a problem. I have AIFF and Apple Lossless and produce things for a radio station. And they won`t accept files with this quality loss.

        If the ReplayGain utility/DSP on the mac is destructive (Spoon will have to confirm this), then copy the AIFF and Apple Lossless to a windows PC. Then, you are able to run the ReplayGain utilty codec on the files, before submitting them to the radio station.

          As a user of the macOS version, all the replaygain codec does to the file is tag the files.

            If convert to [ReplayGain] as the encoder, then the audio is not changed.
