Free online AIFF to TTA converter

1. Source format: AIFF

AIFF (Audio Interchange File Format) is an uncompressed audio format developed by Apple. It is widely used in professional audio production, especially on macOS systems, because it preserves full audio quality and supports standard PCM audio data. AIFF files are common for editing, mastering, archiving, and exchanging studio recordings, but they are relatively large because they store audio without compression.

2. Target format: TTA

TTA (True Audio) is a lossless compressed audio format. It reduces file size while keeping the audio data identical to the original source after decoding. TTA is valued for archival storage and for users who want smaller files without sacrificing quality. Its main advantages are lossless compression and efficient storage, though support is more limited than for more common formats such as FLAC.

3. How to perform the conversion

The most reliable way to convert AIFF to TTA is with a desktop audio converter or command-line tools that support both formats. If you want to convert the file on 101convert.com, you can do it for free without installing any software.

Option 1: Use FFmpeg

FFmpeg is a powerful command-line tool that can read AIFF and write TTA in many builds. Install FFmpeg, then run:

ffmpeg -i input.aiff output.tta

This converts the AIFF file to a lossless TTA file. If your AIFF contains multiple channels or unusual metadata, FFmpeg usually preserves the audio content correctly, though metadata support may vary.

Option 2: Use a dedicated audio converter

Some desktop converters and audio editors can export to TTA directly. Typical steps are:

1. Open the AIFF file in the converter.
2. Choose Export or Save as.
3. Select TTA as the output format.
4. Adjust compression settings if available.
5. Start the conversion and save the new file.

Option 3: Use 101convert.com

Upload the .aiff file, choose TTA as the output format, and download the converted file when it is ready. This is convenient for quick conversions when you do not want to install software.

4. Notes on quality, compatibility, or limitations

AIFF to TTA is a lossless-to-lossless conversion only if the source AIFF contains PCM audio. In that case, the audio quality remains unchanged, but the file size is usually much smaller after conversion. If the AIFF contains compressed or non-PCM data, compatibility may be limited.

TTA support is not as widespread as FLAC or ALAC, so check whether your playback devices or editing software can open TTA files before converting a large library. Also, because TTA is less common, some media players may require an additional codec or plugin.

If you need maximum compatibility, consider whether a more widely supported lossless format would better suit your workflow. If you specifically need TTA, however, it is a good choice for compact, high-quality archival storage.
