Audio RTA vs StemDeck Remote

See the live sound spectrum, find frequency peaks and test your speakers with a practical audio toolkit on your phone. For musicians, sound technicians and installers working with PA systems, studios, instruments and car audio. Use the microphone spectrum as a visual aid when checking sound; the app does not automatically equalize your system. Free basic tools: • Real-time microphone RTA/FFT spectrum • Approximate dB level meter • Frequency generator from 20 Hz to 20 kHz • Subwoofer and stereo channel tests • White noise for general testing Audio Tools Pro is a one-time purchase for lifetime access to advanced tools: waterfall/spectrogram, third-octave bands, manual dB offset, PNG/CSV exports, pink noise and advanced waveforms and sweeps. Access stays linked to your store account. Measurements depend on your device microphone and hardware. Manual dB offset aligns readings to a reference meter; it does not provide certified calibration. Use low volume to protect hearing and equipment. The app does not replace a certified sound-level meter or measure calibrated loudspeaker frequency response. Audio analysis runs on your device; purchases require a connection. The store shows the current Pro price.

StemDeck Remote is the companion app for StemDeck, the desktop app that separates any song into its individual parts — vocals, drums, bass, guitar, piano, and more. Pair the two over your home Wi-Fi and your whole stem library goes with you, ready to mix from your phone or iPad. HOW IT WORKS Open StemDeck on your computer, scan the pairing code (or enter its address manually), and your library syncs over your local network. No account, no cloud upload — StemDeck Remote only ever talks to the StemDeck instance you paired with, on your own network. A PORTABLE MIXING CONSOLE Every song opens onto a real per-stem mixer: • Independent volume, mute, and solo for every stem • Live waveform displays for the whole song and each individual part • Adjust playback speed and pitch independently, with looping • Two mixer styles — a simple, casual view for quick listening, and an Advanced view styled after a hardware mixing console, with level meters and precise faders • Built for iPhone and iPad, in portrait or landscape LISTEN YOUR WAY Download stems for offline playback, keep mixing with the screen off thanks to background audio, and control playback from Control Center or your lock screen — just like any other music app. STAY ORGANIZED Search your library, sort it your way, and group songs into folders as your collection grows. TRY IT FIRST No StemDeck instance handy yet? Check Sample Songs from the home screen to explore the full mixer with a few Creative Commons–licensed tracks (fully credited in-app) — no pairing required. ABOUT YOUR CONTENT StemDeck Remote doesn't separate, download, or source audio on its own — it's a personal remote control and player for a StemDeck instance you run yourself. All stem separation happens locally on your own computer via StemDeck; this app only syncs and plays back stems from the instance you paired with, over your own local network, for your personal use. Nothing is uploaded to us or any third party. You're responsible for only processing audio you have the rights to use. StemDeck Remote requires a StemDeck desktop installation on the same local network to sync your own library. Camera access is used only to scan the pairing QR code; local network access is used only to reach your paired StemDeck instance.
