Which format should I choose?
WAV
Uncompressed PCM. Best for editing, mastering, and archiving where quality matters more than size.
MP3
The universal compressed format. Works everywhere (car stereos, phones, websites). Ideal for sharing and streaming.
OGG
Open and efficient (often Opus/Vorbis). Great for web apps, games, and when you want smaller files with modern quality.
AAC
Preferred by Apple, YouTube, and streaming platforms. Delivers strong quality at lower bitrates than MP3; good for mobile playback.
