Getting Started
What is podcast mastering?
Podcast mastering is a finishing step for a mixed audio file. It can adjust speech level, dynamics, and tonal balance; results depend on the source recording.
How does AI-powered podcast mastering work?
SONE processes a finished audio mix to adjust speech level, dynamics, and tonal balance. The result depends on the source recording.
Is the free tier really free?
Yes. You can use 3 free MP3 masterings each month, with no credit card required.
What is a mastering credit?
Each credit covers one mastering. A credit is used only after the full processing succeeds.
Technical Details
What audio formats are supported?
SONE accepts MP3, WAV, and FLAC files up to 1GB. Output is MP3 or WAV according to your credits.
How long does mastering take?
Processing time depends on file size and the current queue. We will notify you when the completed file is ready.
What loudness standards does SONE follow?
SONE adjusts audio level for a more consistent playback level. Check the delivery requirements of your podcast host before publishing.
Can I master multi-track recordings?
SONE is designed for mastering final mixed audio files. If you have multiple tracks (different microphones, music beds), you should first mix them down to a single stereo file before uploading for mastering.
Can I process files larger than 1GB?
Files must be MP3, WAV, or FLAC and no larger than 1GB.
Security & Privacy
Is my audio secure and private?
Files are handled to provide the mastering service. See our Privacy Policy for details about data handling.
Who owns my audio content?
You retain ownership of your audio. See our Terms and Privacy Policy for details about content use.
Pricing & Billing
What happens when my free credits expire?
Your free credits reset every month automatically. If you've used all your free credits and need more, you can purchase additional credits through our credit packages.
How does AI mastering compare to human mastering?
SONE offers an automated speech mastering workflow. It can adjust level, dynamics, and tonal balance, while the source recording still determines the final result.
Do I need special equipment to use SONE?
You can upload a finished MP3, WAV, or FLAC mix up to 1GB. Cleaner source audio gives the mastering process more to work with.
Troubleshooting
Why does my audio sound different after mastering?
Mastering can change level, dynamics, and tonal balance. If the result sounds too processed, revisit the source mix or try a lighter processing setting.
My file won't upload. What should I do?
First, check that your file is under 1GB and is in MP3, WAV, or FLAC format. Try a different browser if the issue persists. If problems continue, contact support with details about your file and browser.
