SoundPrism

Key Features

• •Per-app volume control with individual sliders for every running application, ranging from 0% to 200%, accompanied by real-time VU meters to show actual audio levels for precise adjustments.
• •10-band parametric EQ for detailed frequency shaping per app, featuring ISO frequencies from 31 Hz to 16 kHz, ±12 dB per band, and 8 named presets for quick adjustments with zero added latency.
• •Multiband compressor offering professional dynamics processing with per-band controls for threshold, ratio, attack, release, and makeup gain, including 6 presets and per-band gain reduction meters.
• •Per-app output routing allowing users to send any application's audio to any output device simultaneously, enabling configurations like Spotify to headphones and Zoom to speakers at the same time.
• •Dual-stream audio recording capable of capturing any individual app's audio in both the original (dry) input and the fully processed (wet) output simultaneously, saving in WAV or M4A format.
• •Complete suite of audio effects including a peak limiter for clipping protection, volume normalization for loudness matching, a stereo widener, crossfeed for headphone listening, and a per-app noise gate.
• •Quick Config profiles that let users save the entire mixer state—volumes, EQ curves, effects, routing—as named setups and switch between them instantly with keyboard shortcuts (⌘⇧1-9).
• •Native macOS design with a menu bar interface, glassmorphic UI, smooth animations, dark mode support, keyboard navigation, and global hotkeys, requiring no drivers or kernel extensions.

Use Cases

• •Podcasters and streamers can isolate and record individual app audio, like a guest's raw Discord audio and the processed mix separately, for clean post-production editing.
• •Gamers can independently control volume for games, voice chat (Discord), and background music (Spotify), routing each to different devices and using the compressor to even out explosive game sounds.
• •Remote workers can manage meeting audio by routing Zoom to speakers, muting Slack notifications, and keeping background music at a low level, with normalization ensuring quiet speakers are audible.
• •Music lovers and audiophiles can apply custom per-app EQ curves to Spotify, use the stereo widener for spatial audio, and apply crossfeed for natural headphone listening, saving profiles for different genres.

Who is this for?

SoundPrism is designed for macOS users seeking granular audio control, including podcasters, streamers, gamers, remote workers, music lovers, and audiophiles. It targets individuals who use applications like Discord, Zoom, Spotify, Safari, Chrome, and games, and who are frustrated by macOS's limited single-volume slider. Users must be running macOS Sonoma or later on Intel or Apple Silicon Macs. The tool appeals to those who value privacy (no data collection), stability (no drivers to break), and a one-time purchase model over subscriptions.
