MP3 Joiner can help you to join audio tracks in numerous formats into a single file. With MP3 Joiner, you can merge MP3 and any number of audio tracks in various formats into a single file saved in a format of your choice. In addition, MP3 Joiner can join MP3 files in lossless mode. If all MP3 files specified are saved with the same bitrate and compression settings as the target track, the tool will take care to keep original audio data without re-encoding or re-compressing, thus preserving maximum audio quality. MP3 Joiner features automatic resampling and format conversion, allowing to join MP3 and other audio files in different formats without worrying about conversion. The tool can decode, resample and re-encode files on-the-fly without you even noticing. This feature is invaluable if your audio collection is stored in a dozen different formats. You can easily join MP3 and other audio files together even if they are saved in different formats or encoded with different codecs, settings and bitrates. MP3 Joiner can take any number of files in all supported formats and output a single track in any format of your choice. You don't need an exact match between your source and destination formats.
