- Nội dung được giữ nguyên
- 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.
Langkah chuyển đổi
- Upload a AC3 file no larger than 1 GB.
- Confirm that M4A is selected as the target.
- Start the conversion. A healthy compatible worker begins processing immediately.
- Download the M4A file and check the result before deleting your source.
Giải quyết vấn đề
- The AC3 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.
