AAC
AAC (Advanced Audio Coding) is a lossy audio codec designed as the successor to MP3. At the same bitrate it usually sounds better than MP3, and it is the standard audio format for Apple devices, YouTube, streaming services, and MP4 video. AAC audio is often stored in M4A or MP4 files.
WAV
WAV (Waveform Audio File Format) is an audio format widely used for recording, editing, mastering, and professional audio production. Most WAV files store uncompressed PCM audio at full quality, although the format can also hold compressed codecs. WAV is supported by most audio editors, DAWs, media players, and operating systems, and PCM WAV files are usually much larger than compressed formats like FLAC or MP3.
What happens when AAC becomes WAV
Source format
AAC is a lossy audio codec that is efficient at moderate bitrates.
Target format
WAV commonly stores uncompressed PCM audio, though the container can hold other codecs.
What changes
Audio samples are decoded from AAC and encoded according to the WAV format and selected bitrate or quality.
- What is preserved
- 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 WAV.
- Codec and quality implications
- Writing WAV without further lossy compression avoids additional codec loss, but it does not restore detail discarded by the AAC encoding.
- Realistic limitations
- Protected audio, malformed headers, unsupported codec variants, or files without a decodable audio stream cannot be converted.
Conversion steps
- Upload a AAC file no larger than 1 GB.
- Confirm that WAV is selected as the target.
- Start the conversion. A healthy compatible worker begins processing immediately.
- Download the WAV file and check the result before deleting your source.
Troubleshooting
- The AAC 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 WAV 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.
