Introduction
A short article describing how to convert Ogg audio files to MP3 with the Pazera Free Audio Extractor. This program is completely free, also for commercial use, and you can download it here.
Ogg, Vorbis, FLAC and MP3
Ogg is an open container format of multimedia, which is maintained by the Xiph.Org Foundation.
In the Ogg files can be embedded audio and video streams, subtitles and metadata. Audio tracks in Ogg files are usually encoded using Vorbis codec, sometimes FLAC, Speex, OggPCM and others. Ogg files with video streams are relatively rare. Most often they are encoded by video codecs: Theora, Dirac, Tarkin, OggUVS. Files with video streams usually have the .ogv extension, while files only with audio streams – the .ogg or .oga extension.
On the web mostly you can find Ogg files with a single audio track encoded by Vorbis codec (Ogg Vorbis), sometimes by FLAC codec (Ogg FLAC). However, no matter which type of Ogg files you have, the program featured in this guide – Pazera Free Audio Extractor – easily handle the conversion all variants of Ogg files.
Ogg files can be played using almost any modern software player (eg. VLC, MPlayer). Unfortunately, most portable and fixed players does not support Ogg files. If you have music collection stored in the Ogg files and your player can not play them, then you need to convert these files to format supported by your device. The choice of MP3 is probably the best because it is currently the most popular audio format and is almost certainly supported by your player.
Conversion Ogg to MP3 using Pazera Free Audio Extractor
Starting the program and adding Ogg files to the processing list
When you install and run the program, the main window will appear.
To convert Ogg files, you must first add them to the processing list. To do this, click the button and specify the desired Ogg files. They appear on the list. Files can also be added using drag and drop.
Parameters of the Ogg to MP3 conversion
When you add files to the list, the next step is to set the output format to MP3 – MPEG-1 Layer 3 in the Audio section.
Then select the desired audio bitrate, which will be used to encode the audio stream from Ogg file to MP3 – this parameter determines the sound quality of the resulting MP3 file.
Bitrate is best set to a value close to the bitrate of the audio stream in the source file. If you use a lower value, you should expect to loss sound quality. However, if you set the bitrate much higher than in the source file, the generated MP3 file will be very large, and the sound quality will be the same as using a lower bitrate.
If you do not want to manually set the audio bitrate, select Auto on the Bitrate list – the program will automatically adjust the audio bitrate to a value close to the bitrate in the source file, and size of the resulting MP3 file should be close to the size of your Ogg file.
The rest of the parameters is best set in the positions Auto, then the program automatically selects the appropriate values.
Using the Volume slider you can adjust the sound level in the resulting MP3 file. When set to 1x, the volume will not change.
Starting conversion
When you add Ogg files to the processing list and set all the necessary parameters, you can already start the conversion by clicking the button. The Conversion window will appear, where you can track the progress of the operation.
With default settings, the converted files will appear in the same directory that contains the source files. You can change output folder in the Output section. Generated MP3 files will have the same name as Ogg files, only the extension is changed to .mp3.
