WAV

It delivers high-quality audio and is widely used in professional environments for music production and sound design. With its uncompressed format, WAV files ensure top fidelity, making them ideal for editing and mastering. Perfect for audio enthusiasts and professionals alike, WAV files guarantee an exceptional listening experience.

GSM

GSM files are used primarily for audio compression in mobile devices, specifically for storing voice data with high efficiency. This lossy compression format offers a reduced file size while maintaining reasonable audio quality, making it ideal for telecommunication applications. Understanding GSM can aid in audio encoding for voice recording and communication tasks.
