MPEG-4 Audio
M4A (MPEG-4 Audio) is a file extension for audio files encoded with Advanced Audio Coding (AAC) or Apple Lossless Audio Codec (ALAC). It's known for delivering high-quality sound in a smaller file size compared to MP3 and is commonly used in Apple devices and software, such as iTunes and iPods.
Free Lossless Audio Codec
FLAC (Free Lossless Audio Codec) is an open-source audio compression format that offers lossless compression, preserving the exact original audio quality. Unlike lossy formats, FLAC retains all audio data, ensuring high fidelity, but with significantly reduced file sizes compared to uncompressed audio formats.
