What happens when AMR becomes M4A

Pinagmulang format

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

Mga Formato

M4A is an MPEG-4 audio container that commonly carries AAC or Apple Lossless audio.

Ano ang mga mababang

Audio samples are decoded from AMR and encoded according to the M4A format and selected bitrate or quality.

Ano ang mag-conserved
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 M4A.
Codec and quality implications
Inspect the output before replacing the source, especially when the formats use different layout, codec, or editing models.
Realistic limitations
Protected audio, malformed headers, unsupported codec variants, or files without a decodable audio stream cannot be converted.

Mga Konversiya

  1. Upload a AMR file no larger than 1 GB.
  2. Confirm that M4A is selected as the target.
  3. Start the conversion. A healthy compatible worker begins processing immediately.
  4. Download the M4A file and check the result before deleting your source.

Mga problema

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 M4A 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 at 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.
