Frequently Asked Questions

Mastering Engineering & Usage FAQ

Clear answers on audio fidelity, DSP processing, in-browser privacy, and ownership rights.

How does Studio Master Pro master audio directly inside my browser?

Studio Master Pro utilizes high-speed Web Audio API pipelines operating in 32-bit floating-point precision. All filtering, dynamic multiband compression, analog Studer tape saturation, 24-band parametric EQ, and true-peak limiting occur client-side in your computer or phone's audio hardware with zero lossy compression and zero round-trip latency.

Are my audio files uploaded to a remote server or cloud database?

No, never. Studio Master Pro is built on a 100% client-side privacy architecture. Your WAV, FLAC, and MP3 files are decoded directly in your local browser sandbox. Zero audio bytes, waveforms, or metadata are ever transmitted, stored, or analyzed on external servers.

Does Studio Master Pro meet streaming loudness standards for Spotify, Apple Music, and YouTube?

Yes. Our master limiting and metering stage is calibrated strictly to ITU-R BS.1770-4 and EBU R128 international broadcast standards. It targets an integrated -14.0 LUFS with a -1.0 dBTP (true-peak) ceiling guard. An integrated 100 Hz detector sidechain filter prevents deep kick drums and sub-bass from needlessly pumping or squashing the mix.

Do I own full rights and commercial royalties to my mastered music?

Absolutely. It's your audio, so it is 100% your right to do anything you want with your audio.

Studio Master Pro is an acoustic mastering tool, not an AI generation platform. Your music is not generated here and never leaves your computer, so we claim zero ownership, zero cuts, zero licensing restrictions, and zero royalties. You retain 100% of your copyright, master recordings, and commercial streaming revenue on every platform.

What audio formats can I import and export?

You can import uncompressed 16-bit, 24-bit, and 32-bit float WAV, AIFF, FLAC, AAC, and high-bitrate MP3 files. Mastered audio can be exported immediately as lossless 24-bit / 48 kHz or 96 kHz WAV with TPDF triangular dither, as well as 320 kbps MP3 files for quick auditioning.

How does the front page load so fast without freezing my browser?

The front page uses a lightweight Lazy-Boot Audio Facade. The visual UI, controls, and spectrum deck display instantly with 0 KB audio thread consumption. The heavy Web Audio DSP engine initializes only when you click 'Launch Mastering Workstation' or drag and drop an audio track onto the canvas. You can also bookmark the dedicated standalone workstation screen at /workstation/.
