Frequently asked questions
Straight answers about files, previews, payment, downloads and privacy.
Which files are accepted?
WAV files using PCM 16, 24 or 32-bit, or IEEE Float 32-bit, mono or stereo, from 44.1 to 192 kHz, up to 150 MB and 30 minutes.
What do I receive?
One professional WAV encoded at 24-bit / 48 kHz with a −1 dB peak ceiling.
When do I pay?
Only after processing and after you have compared the synchronized 30-second preview.
How much does it cost?
Exactly €5.00 for one master. There is no subscription and no additional charge on this site.
Can I download twice?
No. One completed payment unlocks one full WAV download. A second download requires a new payment.
Are model previews real?
Yes. Each selected model is rendered by the mastering engine; switching to a cached model is instant and synchronized.
What happens if processing fails?
You are not asked to pay. Start a new master or contact support if the problem continues.
How long are files kept?
Files are stored temporarily for processing and expire automatically. Do not use the service as permanent storage.
Do I need to own the music?
Yes. You must hold the necessary rights or permission to upload and process the recording.
Does this replace a mastering engineer?
It provides an automated, consistent result. A human engineer remains preferable for detailed artistic revisions or difficult mixes.
