What happens when AMR becomes AAC

स्रोत प्रारूप

AMR is a speech-focused lossy codec commonly found in older phone recordings.

लक्ष्य प्रारूप

AAC is a lossy audio codec that is efficient at moderate bitrates.

What changes

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

क्या बनाए रखा है
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 AAC.
Codec and quality implications
AAC uses lossy compression. A higher quality or bitrate can reduce new artifacts, but it cannot restore detail already missing from the AMR source.
Realistic limitations
Protected audio, malformed headers, unsupported codec variants, or files without a decodable audio stream cannot be converted.

Conversion steps

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

Troubleshooting

The AMR 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 AAC 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.

Privacy and file retention

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.
