How to Convert FLAC to AIFF with FLAC to AIFF Converter?

Most people know MP3, WAV, or even AAC audio formats, but only some have a basic knowledge of FLAC and AIFF unless they are audiophiles. FLAC and AIFF don’t seem to be regularly and massively used in music streaming, that’s why most people are not very familiar with them. But if you are a newcomer of audiophile and want to take a deep dive into music, and be more informed when it comes to deciding what sort of audio format would best serve your purpose? Read on.

Part 1: FLAC vs AIFF

To know more about FLAC and AIFF, introduction of them are as below. Besides, a table was made for you guys to distinguish the difference between them clearly.

What is FLAC?

FLAC stands for Free Lossless Audio Codec, is a popular lossless musical format that emerged in 2001 as an open-source alternative to the other lossless audio formats such as Apple Lossless(ALAC) and Microsoft's WAV (Waveform Audio Format). FLAC offers bit-perfect copies of CDs with half-size optimized, hence it’s always regarded as a high-definition version of MP3 where the compression codec is added and sizing down the file without loss of audio information.

FLAC is perfect and mostly adopted by those people who would like to store their music CDs collection. Technically speaking, it’s the exact replica of the original music file without loss of musical information. FLAC is superior in terms of sound quality and compression rate to the other lossless audio formats and can be played in various audio players. These days most of the record labels are on board with FLAC format available to consumers on the iTunes store.

What is AIFF?

AIFF - Audio Interchange File Format, is one of the most-used audio formats in the Apple Macintosh operating system, often regarded as Apple’s version of WAV files. AIFF offers studio-grade audio recording, sample rate, and bit depth options as WAV files. Containing the original audio data and two uncompressed channel information (stereo and mono), AIFF has a reputation as CD-quality audio. However, that makes the AIFF file take up lots of space for its large file size, a 10-minute song in an AIFF file can occupy 100MB or even more.

Since AIFF stores data in uncompressed, lossless format, it’s commonly used for audio recording. Audio engineers work with AIFF files to make sure the sound quality is preserved in the mixing and mastering process, and exported in compressed format. With no quality loss, AIFF is pure sonic happiness.


Both regarded as lossless audio formats, you might be wondering what the differences and similarities are in features, and which one is better in terms of use. Here we’ll compare these two audio formats briefly.

Type Lossless Lossless
Compression Compressed, based on the lossless audio codec Two uncompressed channels, based on the interchange file format
Sound Quality Compromised but the high-definition audio quality Not compromised audio quality
Compatibility Apple devices only Apple devices, Android, Mac, and Windows
File size Less than AIFF Take up large storage
Usability Ideal for storing and archiving, designed to be downloaded quickly Store music and audio related projects in their original form

Even though FLAC is a strictly compression-based audio format, with high-definition audio quality guaranteed, it sounds just the same as AIFF. It’s a format designed for users to download easily, not audio editing, whereas AIFF works perfectly fine when processed in audio editing without compromising the quality of the audio.
