Free online AIF to TTA converter

Source format: AIF

AIF usually refers to Audio Interchange File Format, an uncompressed audio container developed by Apple. It is widely used in Mac-based audio production, especially in recording, editing, and archiving workflows where preserving original sound quality matters. AIF files commonly store PCM audio and may include metadata such as loop points or markers. Because it is uncompressed, AIF files are often larger than compressed formats, but they are valued for their high fidelity and broad support in professional audio software.

Target format: TTA

TTA stands for True Audio, a lossless audio compression format. It is designed to reduce file size while keeping the audio data identical to the source after decoding. TTA is appreciated for its simple structure, fast encoding and decoding, and good compression efficiency. It is used by audio enthusiasts and in archival or library-style collections where preserving exact audio quality is important but smaller files are preferred over uncompressed storage.

How to perform the conversion

The most reliable way to convert AIF to TTA is with a desktop audio converter or command-line tool that supports both formats. A practical option is FFmpeg, which can read AIF and encode to TTA if your build includes TTA support. If you prefer a graphical workflow, audio editors or converters such as Foobar2000 or fre:ac may also work depending on installed codecs and plugins.

1. Install a converter that supports both AIF input and TTA output.
2. Open the source file input.aif in the program.
3. Choose TTA as the output format.
4. Select the destination filename, for example output.tta.
5. Start the conversion and wait for the process to finish.

If you are using FFmpeg from the command line, the workflow is typically:

ffmpeg -i input.aif output.tta

On the 101convert.com website, you can also convert the file online for free without installing any software.

Notes on quality, compatibility, or limitations

This conversion is lossless only if the source AIF is already uncompressed PCM audio and the encoder preserves the audio without alteration. If the AIF contains unusual sample formats, multiple channels, or embedded metadata, some converters may not carry every detail into TTA. TTA support is less common than formats such as FLAC, so compatibility with players and editors may be more limited. For best results, verify the output by opening the TTA file in a compatible audio player and checking duration, channels, and sample rate.
