Simple, no-frills music player for "oldschool" users who have a music library based on a folder structure instead of tags / metadata. This app is SIMPLISTIC BY DESIGN and does NOT HAVE A LOT OF FEATURES! However, those features that it DOES have work GREAT! IMPORTANT: You cannot use MusicFolder to play music from the regular "Music" app. Instead, you use the iPhone's "Files" app to copy your folder-based music library from your computer (or anywhere else) into MusicFolder. - Supported file formats: mp3, mp4, m4a, aac, alac, wav, adts, ac3, aiff, aifc, caf, snd, au, sd2. - GAPLESS PLAYBACK for all file formats. - Straightforward playlist concept: the playlist always simply consists of all songs in the current folder and its subfolders. - Fast interactive PLAYLIST SEARCH. - Smart folders that show your most listened to or most recently played songs. - GESTURE-BASED CONTROL, no need to look at the screen: swipe up/down to shuffle, swipe left/right to skip, double-tap to play/stop, hold and slide up/down for volume control. - Interactive SCRUBBING through the current song with the realtime seek bar, including waveform preview. - Configurable behavior at the end of a song and on remote control events (headphones / Control Center): skip, shuffle, stop, repeat. - Simple music library transfer and management using the iPhone's Files app. - Optional AUTOMATIC CONVERSION of newly added WAV files to AAC (various quality levels available) or ALAC (Apple Lossless). - Full remote control support for headphones and Control Center. - Full AIRPLAY support. - Supports portrait and landscape orientation. - Selecting a photo from your photo library will auto-generate a theme based on the photo's color structure. IMPORTANT: The app is STRICTLY for FOLDER-BASED libraries and does NOT support ANY kind of tags, cover art, or other metadata inside files. However, for people keeping their music library organized in folders "the oldschool way" and seeking a simple, stable, gapless-capable, no-frills portable player, this app is a godsend!

Four complementary distortion algorithms — Saturation, BitCrush, Ring Modulation, and Downsampling — blended and shaped through an intuitive XY pad. Saturation Shape harmonics using Quantum Distortion’s custom waveshaping saturation. Adjust Drive to set the intensity from subtle warmth to strong coloration, and use Asymmetry to introduce controlled even-harmonic emphasis of vintage tube characteristics. BitCrush Reduce digital resolution using BitCrush and reshape the crushed signal with BitWarp, which bends the quantization curve for additional tonal variation. This combination allows precise control over both the amount of reduction and the character of the resulting digital artifacts. Ring Modulation Introduce inharmonic motion using ring modulation, generated by multiplying the input with a tunable oscillator. Adjust frequency and amount in real time to create anything from light metallic shading to dense, shifting sidebands. Downsampling Lower the sample rate using Downsampling, reducing temporal resolution for classic digital degradation effects. Set the rate down to 200 Hz or introduce Jitter for controlled randomness, adding instability and movement to the downsampled signal. XY Pad Blending Navigate between the four distortion algorithms using the XY pad, allowing smooth transitions or static blends across the processing modes. The background updates to reflect the current region, providing clear visual feedback while exploring hybrid distortion shapes and interactions. Quantum Distortion is an AUv3 audio effect plugin compatible with Logic Pro, AUM, Cubasis, GarageBand and many more. A Desktop version is also available for Windows and macOS (VST3 / AU / AAX).
