  4. Great tool by the way. Love the multithreading and ability to easily retain the folder tree structure.

    Question: what causes this warning in the logs?

    [3/23/2014 6:06:08 PM] Specified process count is too high. This can cause problems. Please consider lowering it.

    [3/23/2014 6:06:09 PM] Number of commands per process are as follows:
    [3/23/2014 6:06:09 PM] Encoder1: 30
    [3/23/2014 6:06:09 PM] Encoder2: 30
    [3/23/2014 6:06:09 PM] Encoder3: 28
    [3/23/2014 6:06:09 PM] Encoder4: 28
    [3/23/2014 6:06:09 PM] Encoder5: 0

    I did a test run with a simple folder structure and less than 120 files. I want to run all of my files through the process and that will be about 7000. Is that going to be a problem?

    I have a quad core intel i5 with 8 GB of ram.

    Just don't want to kick it off and have a bunch of issues.

    It's just a warning to say that you are running a number of parallel processes more than/equal to the number of your CPU's cores. It's generally safe to ignore it.

    Edit: I should make the warning less scary.

  8. Is TAudioConverter's application of ReplayGain a little on the enthusiastic side? Mostly when I try to use it, I end up with a very loud, distorted output. I had a similar problem with an older version of TAudioConverter, but thought it was me doing something silly at the time, and I haven't used it since. Until today. I updated to the current version first. The problem appears to be the application of ReplayGain.

    Here's the ReplayGain info as supplied by MediaInfo from an MP3 I demuxed from an AVI and scanned with Foobar2000.

    Replay gain : -1.90 dB
    Replay gain peak : 0.599490

    I then used TAudioConverter to convert it to AAC while enabling the ReplayGain option (89dB).

    replaygain_track_gain : -88.66
    replaygain_track_peak : 11593.63
    replaygain_track_minmax : 166,228
    replaygain_undo : -57,-57

    Am I reading that all wrong or was the audio volume increased by about 89dB?

    I assume for MP4 and AAC, the audio is converted, then the volume is adjusted according to the ReplayGain results, while for Ogg, only tags are written to the files? Or for Ogg, should the audio also be adusted?

    I ask, because I converted the above MP3 to Ogg while setting a ReplayGain target volume of 89dB, and the result was this:

    Replay gain : -2.74 dB
    Replay gain peak : 0.599139

    I'm not sure why it resulted in -2.74 dB when for the original audio it was only -1.90 dB.
    Then I tried again while setting the target volume to 83dB and this happened:

    Replay gain : -2.74 dB
    Replay gain peak : 0.599139

    Playing the Ogg files with Foobar2000 (I have it set not to adjust the level according to ReplayGain tags) both also sound the same to me despite the different ReplayGain target volume.


    Edit: A little more on ReplayGain..... just for information's-sake.
    I converted an MP3 to MP3 with TAudioConverter while disabling ReplayGain. The log file reported: ReplayGain: -2.5dB
    No ReplayGain information was written to the output file (although I didn't expect that). I then loaded the MP3 into MP3Gain and ran a scan. I checked the tags it created for ReplayGain info:

    Replay gain : -2.43 dB
    Replay gain peak : 0.569263

    And finally I removed those tags and ran a scan with Foobar2000:

    Replay gain : -1.48 dB
    Replay gain peak : 0.569280

    So for reasons I don't yet understand, foobar2000 seems to be the odd one out. It only disagrees with MP3Gain by about 1dB but I'd be interested to know why. Maybe it's a decoding thing? If MP3Gain takes four or five seconds to run a ReplayGain scan on an MP3, Foobar2000 would do it in about half a second.

    It's normal that you see a difference between the RG values between before and after converting to a different format. However it is also plain that there is someting wrong with the way TAC handles AAC RG scans. TAC uses aacgain to scan aac files but I think there is a typo in the code that makes aacgain unable to run a proper scan. Meanwhile, I'm trying to implement a general RG scanner within TAC. So far I managed to scan mp3 and flac files but failed to scan aac files.

    AFAIK, fb2k uses EBU R128 algorithm instead of original RG algorithm so the difference there is also not suprising.

    I didn't know that. And I sort of assumed the EBU R128 algorithm would have a name of it's own, so there'd be ReplayGain scanning and "Similar to Replaygain" scanning", or wherever name they decided to give it. Silly me.

    I went through the changelog and found this for version 1.1.6, so I guess that was when it happened.
    ReplayGain scanner now uses libebur128 for improved accuracy

    Thanks for the info.... and the program!
