What is LUFS normalization?
LUFS (Loudness Units Full Scale) is the industry standard for measuring audio loudness. We can normalize your audio to match platform standards: Spotify and YouTube (-14 LUFS), Apple Podcasts (-16 LUFS), or broadcast (-24 LUFS). This ensures consistent volume across tracks and platforms.
What's the maximum file size?
Free users can upload files up to 500MB. Lite plan supports up to 1GB, and Pro plan supports up to 2GB per file.
What bit rates are available?
We support bit rates from 64 kbps to 320 kbps for lossy formats like MP3 and AAC. Higher bit rates produce better quality but larger files. For most uses, 192-256 kbps offers excellent quality. Lossless formats (WAV, FLAC, AIFF) preserve full quality.
What sample rates are supported?
You can convert to 44.1 kHz (CD quality), 48 kHz (video standard), or 96 kHz (high-resolution). The default preserves your original sample rate.
Can I convert between mono and stereo?
Yes! You can convert stereo to mono (useful for podcasts and voice recordings) or keep the original channel configuration. This option is available in the conversion settings.
