# Audio Fabric Studio: LLM Product Brief Audio Fabric Studio is a web-based audio processing, cleanup, and mastering product for creators, podcasters, musicians, narrators, educators, voiceover artists, and production teams. Primary URL: https://audiofabricstudio.com/ ## Positioning Audio Fabric Studio is a preview-first audio finishing studio. Users upload source audio, choose a sound profile, generate a short before/after preview, and then queue a full master if the result is useful. The service is different from a generic audio enhancer because it uses destination-aware profiles and custom profiles. Profiles encode different expectations for podcasts, music, audiobooks, courses, voiceover, streaming delivery, broadcast, transcription, and restoration. ## Workflow 1. Upload: Drop WAV, MP3, FLAC, M4A, OGG, AIFF, or AIF audio into the Studio. 2. Choose a profile: Pick a preset or saved custom profile that matches the destination. 3. Preview: Generate a short before/after preview and compare the original with the processed result. 4. Master: Queue the full master, save the access token, and download the finished file. ## Plans ### Free Free (Full masters up to 3 min) Try the full workflow with short masters and starter profiles. - Free masters up to 3 minutes - 30 full-render minutes monthly - 30-second before/after previews - 3 starter sound profiles - 2 versions per session - 1 GB storage - Basic metadata preview ### Pay as you go Free up to 3 min (Then $0.09/min; $0.75 minimum paid charge) Occasional mastering with no subscription. - No subscription.

What readers learn: - Choose a source format that preserves quality before processing. - Understand why WAV and AIFF are large, why FLAC is smaller, and why MP3/AAC are delivery formats. - Avoid re-encoding lossy files more than necessary. Checklist: - Upload the highest quality original you can access. - Use MP3 for fast previews and delivery, not as an intermediate archive. - Keep a lossless copy when the master may need future revisions. ### Loudness, LUFS, true peak, and headroom Canonical URL: https://audiofabricstudio.com/kb/loudness-headroom-lufs-true-peak Level: Intermediate; Reading time: 9 min Understand the measurements behind perceived volume, clipping risk, and why a master should be loud enough without being crushed. What readers learn: - Read LUFS, dBFS, dBTP, and loudness range without guessing. - Know why peak headroom matters after encoding. - Use before/after deltas to understand whether the master became clearer, louder, or more controlled. Checklist: - Check whether the profile improved loudness without creating harshness. - Leave true peak margin for delivery formats. - Compare at matched listening volume, not only by which version sounds louder. ### Cleaning noisy recordings without making them sound artificial Canonical URL: https://audiofabricstudio.com/kb/cleaning-noisy-recordings Level: Intermediate; Reading time: 10 min A practical order of operations for hiss, hum, rumble, room tone, mouth noise, reverb, and uneven speech.
