Aurescale: Music Player & EQ

Your music. Your kind of sound.
Play MP3, FLAC and other audio files, shape them with a precise 10-band equalizer, and export the result as WAV or AIFF. Aurescale brings listening and fine-tuning together on your iPhone.

Add more weight to the bass, adjust vocal presence or soften the highs. Start with a preset, then make the sound your own.

PRECISE 10-BAND EQ
• Adjust each band by ±12 dB
• Set center frequency from 20 Hz to 20 kHz and Q from 0.3 to 8
• See the combined effect of your bands in the frequency-response graph
• Use the preamp and automatic headroom to leave room for boosted audio
• Choose presets for bass, vocals and more, or save and recall your own settings
• Make smooth adjustments without stopping playback

EXPLORE HIGH-BAND ENHANCEMENT
Analyze the spectrum and generate estimated content above a detected band limit. Adjust the enhancement amount and harmonic character, then compare with Original mode.

Enhancement generates an estimate. It does not recover the original information lost during compression. Results depend on the source, settings and listening setup.

EXPORT THE SOUND YOU SHAPED
• Use the same processing chain and EQ settings as playback
• Choose whether to apply enhancement and EQ
• WAV: 16-bit, 24-bit or 32-bit float
• AIFF: 16-bit or 24-bit
• Automatic rate selection, or 44.1, 48, 88.2, 96, 176.4 or 192 kHz
• Save to Files and share with other apps
• Keep mono sources in mono

YOUR EVERYDAY MUSIC LIBRARY
Play MP3, AAC (m4a), ALAC, FLAC, WAV and AIFF. Add audio with the file picker or Finder file sharing. Create playlists, reorder tracks, shuffle your collection and keep listening in the background with lock-screen controls.

AUDIO PROCESSING STAYS ON YOUR DEVICE
Playback, analysis, EQ and export run locally. Your audio is not uploaded to our servers for processing, and no separate app account is required. Aurescale plays audio files you already have; it is not a music download or streaming service.

ADS AND OPTIONAL AD REMOVAL
The app shows our own ads for our apps and services, without an external ad network. A one-time in-app purchase removes these ads. Ad loading, purchases and restoration, external links and similar services use a network connection.

Requires iPhone with iOS 17 or later.
Available EQ frequencies and playback output rates depend on your audio setup. Selecting a higher sample rate or bit depth alone does not restore information missing from the source.
