How to convert Audio files in FossaPup? (Solved)

[MrAccident]

(The Solution) - the program QWinFF in Menu → Multimedia.
To create a Preset (to convert to OGG format): in the file /usr/share/qwinff/presets.xml - add (best - in the end of the text; before </presets>):

Code: Select all

<ogg_auto> <label>OGG (vorbis) Automatic settings</label> <params>-acodec vorbis -vn</params> <extension>ogg</extension> <category>Audio</category> </ogg_auto>

An exemplary (advanced)Preset:

Code: Select all

 <ogg_custom> <label>OGG (vorbis) 44.1Khz 240kb bitrate, Auto chan, normalized</label> <params>-acodec libvorbis -ar 44100 -filter:a loudnorm=print_format=summary -ab 240k</params> <extension>ogg</extension> <category>Audio</category> </ogg_custom> <ogg_auto> <label>OGG (vorbis) Automatic settings</label> <params>-acodec libvorbis -vn</params> <extension>ogg</extension> <category>Audio</category> </ogg_auto>

Also, if mhWaveEdit is in your Multimedia selection, you can open the .wav file in mhWaveEdit and then save it as .ogg. I think. I haven't tried that, but mhWaveEdit is a very versatile and powerful tool.

[bigpup]

menu->Multimedia->gWavEdit can also do it.

[MrAccident]

@bigpup gWavEdit - the only option there I see - is "Save As" ― which then says:The file has not changed since last save. Press OK if you want to save it anyway?
Anyway - I would like something more general. I installed AV-Converter; I just don't know how to change the parameters. I'll ask there how to use it; but first I would like to know if there isn't a tool without code; like there was preinstalled, in previous Puppies.

On the "Start" Menu under Multimedia, you will find QwinFF. That app can do plenty of conversions, including to OGG.

@snoring_cat - yeah, of course I didn't check it. :-\ Thanks.
A question: should I leave the settings as they are, or choose manually? Here's an example of the result of leaving them as they are (Sample Rate was on 0Hz, Bitrate on (auto)):
Original file:

Code: Select all

Converted file:

Code: Select all

Hi again MrAccident,

The default presets and values should be fine for most cases. However, audio sound is dependent on the listener. Feel free to test different presets and values. If you want to tweak the audio dramatically, the easier method is to use gWaveEdit...compared to learning ffmpeg arguments (yuck).

I noticed something odd in your attachments. Your audio files don't have the same duration. Do the audio files sound the same to you?

[MrAccident]

@snoring_cat:
I checked again ― the information is wrong; they're both 45 seconds long; and the information in pMediaInfo - is still the same.
What I meant to ask earlier ― is whether the 0Hz and "auto" settings - preserve the original file's quality? Looks like it doesn't; cause I tried now with a 320kbps mp3 file ― and it's still "112 Kbit/s". So I should manually set the same Bit-Rate as the original file?

[bigpup]

@bigpup gWavEdit - the only option there I see - is "Save As" ― which then says The file has not changed since last save. Press OK if you want to save it anyway?

Yes, select save as...
That is just an info statement telling you info.
Then you click OK saying you still want to save it.
The next window provides options at the bottom to select the file type you want to save it as.

[bigpup]

You can use one of these.

Warning:
That big green Start Now is an add for something.

The actual selections are in the big gray rectangle box.

[MrAccident]

@bigpup - snoring_cat already gave me the inbuilt program \ QWinFF.

[snoring_cat]

I think your best solution would be to add some more presets to QWinff

Adding a New QWinff Preset

Add the following to the /usr/share/qwinff/presets.xml text file

Code: Select all

  <ogg_auto>
    <label>OGG (vorbis) Automatic settings</label>
    <params>-acodec vorbis -vn</params>
    <extension>ogg</extension>
    <category>Audio</category>
  </ogg_auto>

Now you will have this preset, which should automatically guess the correct settings for you (referenced off of your input audio file)

This next preset, sets defaults that might be suitable for you. This one is more advanced in that it also normalizes the audio sound level.

Code: Select all

<ogg_custom>
    <label>OGG (vorbis) 44.1Khz 320kb bitrate,  Auto chan, normalized</label>
    <params>-acodec vorbis -vn -ar 44100 -ab 320kb   -af loudnorm=I=-16:LA=11:TP=-1.5</params>
    <extension>ogg</extension>
    <category>Audio</category>
  </ogg_custom>

I'm not sure why QWinFF doesn't have these as presets already.

Techie Manual FFMpeg command line method

You don't have to read the rest of this post. It just includes some manual options to test and convert using FFMpeg. I added this to the post to also show how bitrate and sample rate correlate.

@snoring_cat:
I added the codes in the file, before </presets> (in the end of the text in the file) - like this:

Code: Select all

   <ogg_auto> <label>OGG (vorbis) Automatic settings</label> <params>-acodec vorbis -vn</params> <extension>ogg</extension> <category>Audio</category> </ogg_auto> 
   <ogg_custom> <label>OGG (vorbis) 44.1Khz 320kb bitrate, Auto chan, normalized</label> <params>-acodec vorbis -vn -ar 44100 -ab 320kb -af loudnorm=I=-16:LA=11:TP=-1.5</params> <extension>ogg</extension> <category>Audio</category> </ogg_custom> 

When applying to a file ― is says Failed.

[snoring_cat]

Thanks for noticing that. I didn't notice the "Failed" message in the GUI, but saw the "All tasks have Finished" pop up message. I think that the pop up could be a bit more descriptive, like saying, "All tasks have finished with some failures". Even the output log wasn't showing what failed.

The following should work for you...hopefully. I don't see any problems with it on my side.

Code: Select all

  <ogg_custom>
    <label>OGG (vorbis) 44.1Khz 240kb bitrate,  Auto chan, normalized</label>
    <params>-acodec libvorbis -ar 44100 -filter:a loudnorm=print_format=summary -ab 240k</params>
    <extension>ogg</extension>
    <category>Audio</category>
  </ogg_custom>

  <ogg_auto>
    <label>OGG (vorbis) Automatic settings</label>
    <params>-acodec libvorbis -vn</params>
    <extension>ogg</extension>
    <category>Audio</category>
  </ogg_auto>

[MrAccident]

@snoring_cat - works.
Thanks.
