AAC (Advanced Audio Codec) is a more efficient audio compression format than MP3, offering better sound quality while taking up less storage. It is widely used in streaming, Apple devices, and mobile platforms. AAC supports multiple profiles, making it suitable for various applications, including low-bitrate audio transmission and high-fidelity audio playback.

FLAC (Free Lossless Audio Codec) is an open-source lossless audio compression format that supports multi-format conversion via FFmpeg. FLAC is widely used for high-fidelity audio storage, providing high-quality sound without any loss of audio data, suitable for music production, recording, and audio editing. FLAC files are typically smaller than uncompressed WAV files but retain all the details of the original audio, ensuring the best audio quality.
