OPUS is a modern, open-source, royalty-free audio codec developed by Xiph.Org Foundation and IETF, standardized in RFC 6716 in September 2012. It was designed to replace both Vorbis (for music) and Speex (for voice), combining the best of both into a single codec. OPUS achieves exceptional quality at low bitrates—transparent quality at 128 kbps for music, and near-transparent voice at just 32 kbps. It supports bitrates from 6 kbps to 510 kbps and sample rates from 8 kHz to 48 kHz.

OPUS is the mandatory audio codec for WebRTC, making it the native format for video calls (Discord, Zoom, Google Meet, Teams) and voice messaging (WhatsApp, Telegram). It excels at both speech and music, adapting dynamically to content. OPUS files use the Ogg container (.opus extension) and play in all modern browsers (Chrome, Firefox, Edge, Safari 15+), VLC, and most media players from 2015 onward. For streaming, voice chat, podcasts, and any application where quality-per-bit matters, OPUS is the current state of the art.
WAV (Waveform Audio File Format) is an uncompressed audio format developed by Microsoft and IBM in 1991. It stores raw PCM (Pulse Code Modulation) audio data, preserving every sample from the original recording without any quality loss. WAV supports 16/24/32-bit depth, sample rates from 8 kHz to 192 kHz (commonly 44.1/48 kHz), and up to 65,535 channels. It's the standard working format for audio professionals in recording studios, broadcast facilities, and sound design workflows worldwide.

The main tradeoff is file size: a 3-minute stereo track at CD quality (44.1kHz, 16-bit) is approximately 30 MB. While this makes WAV impractical for streaming or portable devices, it remains essential for editing, archiving, and any workflow where audio quality is paramount. Converting to MP3 reduces file size by 90% or more while maintaining perceptually transparent quality for most listeners.

How are credits calculated for this conversion?
Cost: 1 credit per 5 minutes
How it works:
- Files up to 5 minutes: 1 credit (minimum)
- 6-10 minutes: 2 credits
- 11-15 minutes: 3 credits
- 16-20 minutes: 4 credits
Example: A 10-minute file = 1 credit. A 180-minute (3h) audiobook = 36 credits.
Why per-minute? Audio conversion time scales with content duration, not file size. Longer audio requires proportionally more processing.
What are my daily and monthly credit limits?
Credit allocations vary by account tier:
| Tier | Daily Limit | Monthly Limit |
|---|---|---|
| Free | 50 credits/day | — |
| Pro | — | 10,000 credits/month |
| Business | — | 30,000 credits/month |
Daily credits (Free tier, including guests) reset every day at midnight UTC. Monthly credits (Pro & Business) reset on your billing cycle date.
Note: With 1 credit per 5 minutes, audio files under 5 MB cost 1 credit each. Pro users can convert 10,000 audio files per month.
