تنسيق المصدر
AIFF commonly stores uncompressed PCM audio and can be much larger than compressed audio.
AIFF
AIFF is a file format supported by Convertr for online file conversion workflows.
M4A
M4A is a file format supported by Convertr for online file conversion workflows.
What happens when AIFF becomes M4A
تنسيق الهدف
M4A is an MPEG-4 audio container that commonly carries AAC or Apple Lossless audio.
ما هي التغييرات
Audio samples are decoded from AIFF and encoded according to the M4A format and selected bitrate or quality.
- ما الذي يُحفظ
- 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.
خطوات التحويل
- Upload a AIFF 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.
حل المشاكل
- The AIFF 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.
الخصوصية والحفاظ على الملفات
