Lacquer vs Rewamp
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Lacquer
This app analyzes audio files to verify their true resolution, distinguishing genuine high-resolution music from upscaled or re-encoded content. It decodes and examines the audio data directly, providing detailed evidence of its quality and signal path.
- Audio file quality verification
- Real-time audio decoding and analysis
- Signal path visualization
- Headphone EQ and correction
- Plays various audio formats
- Gapless playback and crossfade

A lot of the "hi-res" music out there isn't. A file can say 24-bit/96kHz on the label and still be an MP3 that somebody re-encoded into a FLAC container and sold on. Your player shows the badge and has no idea. Lacquer does. It reads the audio itself — not the file name, not the metadata tags — and tells you what is actually inside. QUALITY CHECK Every lossless file you import is decoded and analysed on your phone, with an FFT running on Apple's Accelerate framework. Nothing is uploaded. There is no account. The verdict does not come from a single cut-off number. Three things are weighed: how steeply the top end falls away, whether that fall makes sense for the sample rate the file claims, and whether the same edge sits in the same place across different parts of the track. Real recordings fade out, and they wander. An encoder's cut does not. It is also careful about what it says. A flagged file reads "may be upscaled", never "fake" — an old master or a quiet orchestral recording can look suspicious for perfectly honest reasons. When a file's top end simply ends too low for the evidence to point either way, Lacquer says it cannot tell, rather than guessing. Every verdict shows the number it was based on and the line that number was measured against, so you can look at the evidence and disagree. SEE THE EVIDENCE Tap the artwork while a track is playing and it turns over. On the back is the file — format, bit depth, sample rate, size — and under it the device you are actually listening on and the rate coming out of it. Below that is everything between the file and your ears: EQ, speed, sample-rate conversion and Bluetooth re-encoding. A file that failed the check does not get to show off the specs it claims. The label switches to the evidence instead: the claim struck through, where the sound really stops, how wide the roll-off is, and the threshold that decided it. WHAT REACHES YOUR DAC A signal path sheet shows file, engine and output side by side and says plainly whether anything is being resampled on the way through. Switch on "match the file's rate" and Lacquer asks the output to run at the file's own sample rate, and takes the equalizer and speed controls out of the path entirely. iOS will not tell an app which rates a connected DAC accepts, so Lacquer finds out the only way there is: it asks for each rate in turn and reads back what the hardware actually did. The answer is remembered for that device. TUNED TO YOUR HEADPHONES Import the ParametricEQ.txt measured for your headphone model and Lacquer plays everything through that correction. Pair it with a device and it turns on by itself when you connect. Add up to 10 bands of your own on top, dragged right on the graph, or pick a sound style in one tap. The preamp drops automatically so boosts never clip. THE REST OF THE PLAYER Lacquer plays FLAC, ALAC, WAV, AIFF, MP3, AAC and m4a from your own library, gapless, with crossfade, and shows the lyrics embedded in your files. Bring music in from the Files app, from your DRM-free iTunes tracks, or straight off your own server — Lacquer has native SMB and WebDAV clients for the NAS boxes that never appear properly in Files. There is an Apple Watch companion for playback control. Everything stays on the device. It works on a plane. LACQUER PRO Unlocks Quality Check results for every file, headphone correction, the parametric equalizer, unlimited imports, cloud import and an ad-free app. Weekly, yearly, or a one-time lifetime purchase. The free version shows ads. Lacquer never plays DRM-protected tracks and never bypasses any protection. It is a player for music you already own.

Rewamp plays the music of the machines that made it. Not recordings — emulation. A .sid runs on an emulated 6581, a .nsf on the NES sound hardware, a .mod through an Amiga Paula mixer. You hear the chip doing the work, as it did on the original hardware. FROM THE ARCHIVES THAT KEEP THIS MUSIC ALIVE For decades, volunteer archivists have collected and documented computer and game music so that none of it gets lost. Rewamp plays their work directly: HVSC, Modland, Amiga Music Preservation, UnExotica, SNDH, ASMA, VGMRips, ZXArt and more, with credits and demoparty results from Demozoo. Search by title, artist, group or platform, browse by collection, party or year. Every track keeps its original file and its credits. Your own files play too, including folders and archives (ZIP, 7z, RAR, LHA). OVER 1,200 FORMATS Tracker modules, 300+ Amiga formats, C64 SID, NES, Game Boy, SNES, GBA, Nintendo DS and N64, Sega and arcade VGM, MSX, ZX Spectrum, Atari ST and 8-bit, PC-98, X68000, AdLib, MIDI with SoundFonts or MT-32 emulation, 700+ game stream formats, and more. SEE THE SOUND Seven native visualizers: oscilloscope per voice, spectrum, notation, piano, tracker patterns and Milkdrop (projectM). Mute any voice, isolate a channel, change the tempo without changing the pitch. YOURS, OFFLINE Downloads play without a connection. Playlists, favourites and listening stats work on the device alone. A free, optional account syncs them across your devices. • Gapless playback or crossfade • Lock-screen and headset controls • No ads • 18 languages Rewamp is the successor to Modizer, rebuilt from the ground up.
