Can I compare before and after?
Yes. Generate a short before/after preview before approving a full master.
Is AI used to transform my audio?
No. Audio Fabric uses profile-based audio processing, mastering, cleanup, loudness, EQ, dynamics, and format conversion. It does not generate, replace, clone, or reinterpret your performance with AI.
Will the finished file have an AI footprint?
No. Because the transformation is not AI-generated, Audio Fabric does not add an AI watermark, AI provenance marker, synthetic audio layer, or generated-content footprint to your output.
What happens to my metadata?
When the source file and selected output format support metadata, Audio Fabric preserves available titles, artists, album details, artwork, and common tags. It does not invent or add new metadata unless you enter or edit it yourself.
Can a sound profile change the words, melody, or performance?
No. Profiles adjust sound treatment such as level, tone, noise control, compression, loudness, sample rate, and delivery format. They do not rewrite lyrics, change speech, alter notes, or create new performances.
Is the audio health check AI?
The health check is a measurement and recommendation step. It looks at technical signals such as loudness, peaks, duration, and available metadata to suggest a profile. The actual audio transformation remains profile-based processing.
What file types are supported?
WAV, MP3, FLAC, M4A, OGG, AIFF, and AIF are supported.
Can I try multiple profiles?
Yes. You can queue different profiles for the same source file and compare the resulting masters.
What are custom profiles?
Custom profiles save your preferred EQ, dynamics, filters, sample-rate, and loudness settings.
Can I retrieve a master later?
Yes. Guest renders produce access tokens that can be used to check status and download completed masters.
Is there an API?
Yes. API access supports batch uploads, preview renders, full renders, status checks, and webhook workflows.
