What happens when AU becomes MP3

Format sursă

AU is the audio source or target format for this conversion path.

Formatul țintă

MP3 is a widely supported lossy audio format.

Ce schimbări

Audio samples are decoded from AU and encoded according to the MP3 format and selected bitrate or quality.

Ce este păstrat
Duration and audible content are preserved, subject to decoder support and any settings you change.
What may be lost
Tags, embedded artwork, chapters, and codec-specific metadata may not map to MP3.
Codec and quality implications
MP3 uses lossy compression. A higher quality or bitrate can reduce new artifacts, but it cannot restore detail already missing from the AU source.
Realistic limitations
Protected audio, malformed headers, unsupported codec variants, or files without a decodable audio stream cannot be converted.

Etapele de conversie

  1. Upload a AU file no larger than 1 GB.
  2. Confirm that MP3 is selected as the target.
  3. Start the conversion. A healthy compatible worker begins processing immediately.
  4. Download the MP3 file and check the result before deleting your source.

rezolvarea problemelor

The AU file is rejected or will not open.
Confirm that the file is not empty, password-protected, or corrupt and that its real format matches the extension.
The MP3 file is larger than expected.
Choose a more efficient codec or lower quality setting when available. Lossless and uncompressed targets are often larger by design.
The result has no sound or will not play.
Try a broadly supported target codec and verify that the source contains a decodable audio stream.

Confidențialitate și păstrarea fișierelor

Uploads and converted files are processed automatically and irreversibly deleted within 24 hours. You can delete them sooner with the delete control. Convertr does not read, mine, sell, or manually review file contents.
