Car DSP Music Player
$9.99
Simple look, serious sound. 28-band EQ, tone control, auto in-car correction. With a USB DAC, play hi-res at native rate or upsample to 384kHz. No ads, one-time purchase.
A simple music player that plays songs from your iPhone's Music library, browsable by playlist, artist, song, or album. Perfect for listening during your commute or at home — and the moment you get in the car, it transforms into a true car audio experience.
■ 28-Band Equalizer & Tone Control
Fine-tune your sound with a 28-band graphic equalizer powered by digital signal processing (DSP). A dedicated "Tone Control" screen, accessible right from the full-screen player, lets you quickly adjust just bass and treble — intuitive enough to use even while driving. Genre presets (Jazz, Vocal, and more) are also included.
■ Automatic Cabin Acoustic Correction
Using your device's microphone, the app records a sweep tone measurement and analyzes the acoustic characteristics unique to your car's cabin (peaks and dips caused by reflection and resonance) to automatically generate a correction curve. Choose how strongly the correction is applied from several patterns, or fine-tune it manually afterward, just like an equalizer. You can preview and adjust the correction curve anytime, without interrupting your music.
■ Multi-Layer Clipping Protection
A combination of input pre-attenuation, dynamic gain management, and an output limiter detects and suppresses clipping during loud playback, keeping your sound clean.
■ Hi-res output via USB DAC
With a USB DAC connected, choose how to play in the Sound tab's "Output rate":
- Native: outputs hi-res tracks at their original sample rate (no rate conversion in the app)
- Auto upsampling: upsamples by whole-number ratios up to 384kHz (352.8kHz for the 44.1kHz family)
The full-screen player shows the track format and the actual output rate at a glance.
* Available rates depend on your DAC.
■ Other Features
• Create playlists of your favorite songs
• Spectrum display on the full-screen player
• Playback control from the lock screen and Control Center, with background playback support
• Supports Bluetooth and USB DAC connections
• Japanese and English interface support
■ Supported Files
The app plays songs already added to your iPhone's Music app (AAC, MP3, Apple Lossless, WAV, AIFF, FLAC, and more). Songs protected by DRM, including Apple Music tracks (even downloaded ones), cannot be played. Please add and sync the songs you want to play to your Music library beforehand.
On your commute, at home, or in the car — enjoy your favorite songs, tuned exactly the way you like, wherever you are.
