FAQs
Why WAV instead of MP3 for voice messages?
If the next step is transcription or editing, many tools handle WAV most completely; MP3 is for sharing and archiving. Match the downstream use: WAV into tools, MP3 out to people.
Voice notes are low quality anyway — does WAV matter?
Yes. WAV doesn't raise quality; it gives downstream processing a lossless lane — transcription, denoising, and cutting all run clean, then you compress to whatever format you need.
Which OPUS sources are supported?
Discord, WhatsApp, and Telegram voice notes, call-recorder apps, and any .opus or Opus-encoded .ogg file decodes fine.
