What audio format is commonly used in professional AV systems?

In professional AV systems, a variety of audio formats can be utilized, and they often cater to different requirements such as sound quality, file size, and compatibility with systems. The inclusion of MP3, AAC, and WAV among the options reflects this diversity.

MP3 is a widely used compressed audio format that balances file size and sound quality, making it suitable for many applications where storage space is at a premium and high audio fidelity is not the primary concern. AAC, or Advanced Audio Codec, offers better sound quality than MP3 at similar bit rates, which is advantageous in professional contexts where sound fidelity is critical while still keeping file sizes manageable.

WAV, on the other hand, is an uncompressed format that delivers high-quality audio, making it a preferred choice in professional settings where the highest possible audio fidelity is required, such as recordings and broadcasts. It is more suitable for scenarios where storage capacity is not an issue.

Considering that all three formats—MP3, AAC, and WAV—are relevant in various contexts within professional audio-visual systems, selecting an answer that includes all of them acknowledges this versatility and the necessity of different audio formats matching specific needs in professional AV environments. Thus, the answer reflects a comprehensive understanding of the types of audio formats
