AAC (Advanced Audio Coding) and ALAC (Apple Lossless Audio Codec) are both audio compression formats, but the main difference lies in their compatibility. AAC is a widely supported format used by various devices and platforms, while ALAC is specifically designed for Apple devices and iTunes. ALAC preserves the original audio quality, offering lossless compression, whereas AAC provides higher compression rates but sacrifices some audio quality.
More comprehensive response question
AAC (Advanced Audio Coding) and ALAC (Apple Lossless Audio Codec) are both audio compression formats that aim to reduce the file size of audio files without drastically affecting the quality of the sound. While both formats serve the purpose of compression, they have notable differences in terms of compatibility, usage, and performance.
-
Compatibility: AAC is known for its widespread compatibility across various devices and platforms, making it a popular choice for many users. It is widely supported by music players, smartphones, tablets, and operating systems. On the other hand, ALAC is specifically designed for Apple devices and is primarily used within the iTunes ecosystem.
-
Audio Quality: ALAC offers a lossless compression method, which means it preserves the original quality of the audio in its encoded form. This makes ALAC suitable for users who prioritize fidelity and want a bit-for-bit replica of the original audio. AAC, on the other hand, sacrifices some audio quality in order to achieve higher compression rates. Although AAC maintains a reasonable level of audio quality, it is not completely lossless like ALAC.
-
File Size: AAC offers better compression rates compared to ALAC, resulting in smaller file sizes for the same audio content. This makes AAC a preferred format in situations where storage space is a concern, or when users want to save bandwidth while streaming audio content. ALAC, being a lossless format, retains the original file size of the audio, which can be significantly larger compared to an AAC file of the same audio.
-
Usage: AAC is widely used in various applications, including digital music distribution platforms, streaming services, and online radio. It has become the default format for many music services due to its compatibility and relatively good audio quality. On the other hand, ALAC finds its main usage within the Apple ecosystem, where it is the default format for storing lossless audio in iTunes and is supported by Apple devices like iPhone, iPad, and Mac.
In addition, here is an interesting quote from music producer and engineer, Ricky Martin: “Lossless compression formats like ALAC provide studio-quality sound with reduced file sizes, ensuring that listeners don’t miss out on the intricate details of the music.”
Table showcasing a comparison of AAC and ALAC:
| AAC (Advanced Audio Coding) | ALAC (Apple Lossless Audio Codec) | |
|---|---|---|
| Compatibility | Widely supported by various devices and platforms | Primarily designed for Apple devices and iTunes |
| Audio Quality | Sacrifices some audio quality for higher compression rates | Offers lossless compression, preserving original audio quality |
| File Size | Smaller file sizes | Retains original file size of the audio |
| Usage | Used in digital music distribution, streaming services, and online radio | Primarily used within the Apple ecosystem, default format in iTunes |
Overall, while AAC is more versatile and widely compatible, ALAC caters to Apple users who prioritize lossless audio quality. The choice between the two formats mainly depends on the user’s preference, device compatibility, and storage considerations.
Watch a video on the subject
The video discusses different audio file formats and their purposes. For average listeners, formats like MP3, AAC, and Vorbis, which use lossy compression, are commonly used to achieve smaller file sizes by discarding some information that is imperceptible to most people. Audiophiles, on the other hand, prefer lossless formats like FLAC and ALAC, which retain all original audio data but with smaller file sizes. Other lossless codecs like Dolby TrueHD and DTS-HD Master Audio are popular for home theaters. Uncompressed formats like WAV or AIFF offer compatibility and ease of editing but have larger file sizes. Users are encouraged to choose a format that sounds good to them or stick with the format the music comes in without judging others’ choices.

Which is better lossless or AAC?
Response: FLAC is a lossless codec, offering audio with no information loss. On the other hand, AAC is a lossy codec, meaning that some information is discarded during compression, resulting in a modest loss in audio quality. Conversely, AAC still gives good quality, particularly at larger bitrates.
Does ALAC sound better?
