MP3 is one of the most widely used audio formats, offering lossy compression with good sound quality and small file size. It revolutionized music distribution and remains the standard for digital music playback across nearly all platforms and devices.
GSM is a lossy audio format optimized for voice compression, often used in telephony. It provides clear speech at low bitrates, making it suitable for phone recordings, VoIP applications, and legacy mobile systems.
