Instead of decoding DSD to PCM, the original 1-bit stream is carried inside a 24-bit word to the DAC. A DAC that recognizes the marker strips it and feeds the 1-bit stream straight to its delta-sigma stage. - DoP needs an external DAC that understands it and accepts the carrier rate (176.4 kHz for DSD64, 352.8 kHz for DSD128). When that isn't the case the track plays as decoded PCM instead, and the signal path says so rather than failing quietly. - Connecting a DAC that can carry DoP now asks whether to use it, rather than switching silently — DoP turns the whole DSP chain off. The answer is remembered per device, and the question is only asked when the route genuinely accepts the carrier rate. - The signal path now has a "Device" row: the sample rate the output device is actually running at, plus its name, with a "Resample" row when the OS is converting. This is what the hardware accepted, not what the app requested. New — Playlists - CUE sheet support, so an album ripped as a single file plays as tracks. Each track is a region of the file, and seeking, gapless and crossfade all work within it. CUE sheets over DSD (SACD rips) too. - M3U / M3U8 playlist support. - Playlists appear in the Library tab between Folders and Tracks, found anywhere in the library — including inside album subfolders, where CUE sheets usually live. - Playlists written in legacy encodings (a CUE from a Korean Windows box is CP949, not UTF-8) load correctly. Entries pointing at files this device doesn't have are left out rather than shown as dead rows. New — External folders - Under Library ▸ + ▸ Add External Folder. Any folder reachable in the Files app can be added to the library — including a NAS share, if you've connected the SMB server in Files. Files are read where they are, not copied in, and the folder survives relaunches. - External folders are read-only: no rename, import or delete, and the swipe action is "Remove from Library" rather than "Delete". Removing one never touches a file on that storage. - When the server is off or the drive is unplugged, the folder stays in the list marked Unavailable and comes back on its own once reachable. New — Spectrum analyzer - The spectrum analyzer is rebuilt: far finer bars, smooth 60 fps motion, and an immediate response to the sound. - Detail (bar count), under Settings ▸ Spectrum Analyzer ▸ Detail: Standard (32), Fine (64) or Ultra (96). Defaults to Fine. - Frame rate 30 / 60 FPS. 60 is the default — smoother and more immediate; 30 saves CPU. - Auto-Level eases the reference to recent loudness so quiet passages stay visible. Off falls back to a fixed −60…0 dBFS range. - A peak-hold cap sits above each bar, marking the level it just passed. - The low end (20–50 Hz) reads as a natural curve instead of a staircase. - All of the above live under Settings ▸ Spectrum Analyzer. New — Library - The track list names the dominant instrument instead of the genre. The same on-device model was often wrong about genre and holds up far better on instruments, so the genre guess is gone entirely. - The filter follows: pick from "Instrument" at the top of the Library. A track that comes back with two (Guitar · Drums) is matched by either. - Re-analysis is now a press and hold on the "Instrument" button. It walks the whole library from scratch, so it asks first rather than starting on a stray tap. (The entry under + is gone.) New — Elsewhere - Convolution Reverb now links to two free IR libraries — EchoThief and OpenAIR — with a note on what kind of space each one holds. ### 1.2.0 — 2026-07-19 New - Virtual Reverb (Pro), under Settings ▸ Spatial. Studio, Live Club, Concert Hall and Cathedral presets with an amount control (defaults to Live Club at 35%). - Virtual Reverb rides on HRTF rendering to wrap the sound into an out-of-head space, so turning it on turns HRTF on, and turning HRTF off turns it off. - A high-pass (~180 Hz) on the Virtual Reverb keeps the low end tight and adds space only to the mids and highs, so bass never turns to mud. - Convolution Reverb (Pro), under Settings ▸ Convolution Reverb. Load an IR file (WAV/AIFF) and the signal takes on that real measured space's reverberation — a hall/cathedral IR gives the most realistic result. FFT-partitioned, so multi-second tails run in real time; a Mix control blends dry and wet, and the IR is level-normalized so it can't blast. - Both reverbs are baked into FLAC conversion, with the tail allowed to ring out instead of being cut off. And a few bugs have been fixed. ### 1.1.2 — 2026-07-08 This release is all about startup speed: library scan results are now saved on device, so after the first launch your library appears the moment the app opens. Improved - Faster app startup. Track metadata (tags, album art, format info) is cached on device instead of being re-read from every file on every launch — only new or changed files are parsed. The bigger your library, the bigger the difference. - The full-screen "Scanning…" message now appears only on the very first scan, when there is nothing to show yet. Later refreshes (relaunch, import, move, pull-to-refresh, the ↻ button) update the visible list quietly in the background. - Refreshes are lightweight: adding, deleting, or editing files only rescans those files, and cache entries for removed files are cleaned up automatically. Tracks in subfolders get the same treatment. - Settings ▸ "Use Filenames as Titles" now applies instantly in both directions. The embedded title tag is always kept alongside the filename, so flipping the toggle no longer rescans the library. (Previously every flip re-read all files.) ### 1.1.1 — 2026-07-08 This release focuses on localization, FLAC metadata, and library convenience: nine new display languages (eleven in total), proper album art and tags on FLAC files, and easier filename-based library organization. Improved - Added nine display languages: Chinese (Simplified and Traditional), Japanese, German, Italian, French, Portuguese, Spanish, and Arabic — eleven languages in total alongside English and Korean. Switch instantly in Settings ▸ Language; the list is alphabetical with English (the default) on top. Control direction (sliders, transport) stays the same in every language. - New "Use Filenames as Titles" option in Settings. When enabled, tracks are titled by their file name (without extension) instead of the embedded title tag — handy if you organize your library by renaming files. Flipping the toggle rescans the library on the spot. - Converted FLAC files are now named "Track-FLAC.flac" (previously "Track (FIDEL).flac"). - Pull down inside a folder to rescan the whole library (pull-to-refresh). - Tidied the bottom selection bar shown when long-pressing a track: smaller button labels (Convert, Move to Folder, Move to Library). And fixed some bugs. ### 1.1 — 2026-07-06 This release adds features and stability: selectable FLAC conversion bit depth and an in-app audio output picker, plus a full audit of the playback engine, library, and audio chain that fixed more than twenty issues. Improved - FLAC conversion bit depth is now selectable (24-bit default / 16-bit). 16-bit files are about a third smaller, with noise-shaped dither applied at the final quantization to keep quiet passages distortion-free. Silence and untouched 16-bit signal are preserved bit-exact. - Removed the "Bit Depth Expansion" playback setting. The playback path is 32-bit float end to end, so it never reduces bit depth — the stage had nothing to protect. Dither now lives where it actually matters: the 16-bit FLAC conversion. As a bonus, the BIT-PERFECT badge is now reachable with default settings. - Tap the Audio Output row in Settings to pick the output device (AirPlay, Bluetooth, built-in speaker) right in the app. - FLAC conversion now embeds title/artist/album/genre tags and cover art, and DSD (DSF/DFF) files can now be converted to FLAC. - Faster DSD start-up: the conversion cache is reused across launches, and orphaned copies no longer pile up on every launch — saving storage. - Importing large folders no longer freezes the UI (copies run in the background). - Imports and moves rename on name collision ("Name 2") instead of overwriting; failed items are reported in an alert. - Standard-mode EQ bandwidths are now accurate, so the curve matches the Linear Phase modes (bands used to apply ~30% narrower). - A more honest BIT-PERFECT badge: convolution (room correction), channel balance, polarity inversion, and loudness compensation now disqualify the badge — and Bit-Perfect Mode actually forces those stages transparent. And fixed bugs. ## More apps by JINHONG KIM - [단모음키보드 럭럭고](https://appshunter.io/ios/app/id6759483875) - [Binaural Beats: Focus & Sleep](https://appshunter.io/ios/app/binaural-beats-focus-and-sleep/id6775225093) - [CardVault: Biz Card Scanner](https://appshunter.io/ios/app/cardvault-biz-card-scanner/id6776257121) All apps by JINHONG KIM: https://appshunter.io/developer/1878939629 ## Related topics [upsampler](https://appshunter.io/ios/topics/upsampler) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
