Advanced equalizer
Shape every detail.
Switch between graphic and parametric editing, start with carefully designed factory profiles, build your own profiles, or let BitaBit choose a curve automatically from the track’s genre. The live response view shows how your choices shape the sound and how much headroom remains.
Parametric editing
Set filter type, frequency, gain, and Q when you want finer control.
Open the equalizer directly from the Music Player.
Profiles
Start with one of 17 localized factory profiles, create and edit your own, or map profiles automatically by genre.
Live response
See the effective curve and estimated headroom, with manual or automatic safe input trim, before you listen.
A/B comparison
Hold to compare your current processing with the neutral signal without losing your settings.
Output Correction
Tailored where it matters. Neutral where it doesn’t.
Optional output correction can apply bundled profiles to supported AirPods, known headphones, iPhone speaker categories, and recognized car outputs. Go beyond tone shaping with channel controls, headphone crossfeed, short FIR convolution, and true-peak output protection.

Radio Controls
Move through stations without leaving the player.
Previous and Next now move between stations in the stable list you were browsing, so favorites, recent stations, and search results can be explored directly from the player.
Stay in the list you chose
Choose a station from Favorites, Recents, or Search, then continue through that same list.
Previous and Next
Move to the neighboring station without returning to the radio browser.
Controls beyond the screen
The same navigation works with compatible system and vehicle media controls when those controls are available.
Technical Details
Understand the active signal path.
BitaBit explains the source, decoder output, active processing, and the output information iOS can report. When the equalizer is active, it can show the selected mode and profile, applied filters, gain stages, response headroom, limiter activity, and filters bypassed near the source’s Nyquist limit.
Start with the file or stream
See source format, sample rate, and bit depth when that information is available.
Know what enters processing
Decoded signal information is kept distinct from the original source details.
See what BitaBit is doing
Graphic or parametric mode, active profile, genre selection, filters, correction, and gain stages appear as BitaBit processing state.
Read the estimate honestly
Effective response and headroom are clearly identified as estimates, alongside applied filters and limiter diagnostics.
Use what iOS can report
Available output information is labeled as reported by iOS, and unavailable values stay unavailable.
Local and remote stay distinct
The screen separates locally processed audio from remote playback paths so one is never mistaken for the other.
Measured, reported, estimated, and unavailable values are labeled separately—so the screen explains what is known without turning an estimate into a promise.
BitaBit at a glance

Everything careful listening needs.
Nothing that gets in the way.
A deliberately short audio path for the music you own, the stations you find and the shows you follow. No noise, tracking or pressure from another platform.
A clear path to the music
BitaBit keeps its own route deliberately short, avoids hidden app-side re-encoding and lets you see what the source and output are doing.
Radio worth wandering through
Find a new station, return to an old favorite and see live titles, artwork and stream detail whenever the broadcast shares them.
Keep the shows. Lose the feed.
Follow, download and resume with intent. Bring subscriptions with OPML and set the pace that works for you.
Real-time synthesis
VGM/VGZ files are synthesized live with libvgm and more than 40 retro chips. They are generated as you listen, not pre-rendered audio.
Details when you want them
Read the route in sample rate, bit depth and output data. Or get the same answer in plain language.
Pick up where you left off
Your selected files, playlists and queue are ready when you come back, not rebuilt from scratch.
25 real extensions
FLAC, ALAC/M4A, MP3, WAV/AIFF, DSD, Opus, Ogg Vorbis, APE, TTA, WavPack and VGM/VGZ. Every one uses an explicitly registered decoder.
Private by default
No account or analytics SDK. Your local library stays on iPhone; online sources connect directly to their providers.

Music has a shape
Eight ways to see what you hear.
Real-time FFT analysis gives every track a living visual language: 64 logarithmic bands, waveform feedback and motion that stays out of the music’s way.

The waveform is there to help: read a track’s dynamics, find a section and land exactly where you meant to.
The proof is in the route
One signal. Two useful ways to read it.
Go as deep as you want. BitaBit can show the numbers behind the route, then say plainly whether your music is arriving as it should.
What the signal is doing
Source, route and output. Side by side.

Output routeUSB Audio · 96 kHz reported by iOS · bit depth when available
VerdictBitaBit processing state: no app-side sample-rate reduction, dithering or codec conversion reported in this route.
For people who like to know
No mystery between file and headphones.
Codec, sample rate, bit depth, output route and a quality verdict are all there when you want them. If the signal changes, you can see where and why.
DSD → PCM
DSF and DFF are prepared for playback, with a clear readout when they meet a PCM path or a compatible USB DAC.
VGM · AVAudioSourceNode
VGM/VGZ is synthesized live through libvgm and AVAudioSourceNode: 40+ retro chips, without flattening the track first.
FFT · Accelerate
vDSP groups the signal into logarithmic bands so visualizers can respond without getting in playback’s way.
Controlled AVAudioEngine
Files and live synthesis take a short route to output, while your queue and secure file access are ready when you return.
Signal path
AVAudioFile→PlayerNode / SourceNode→MainMixerNode→OutputNode→Hardware
Local files travel from decoder to AVAudioPlayerNode. VGM/VGZ uses AVAudioSourceNode with buffers prepared before render, keeping the real-time audio thread focused on playback.
Questions
The details, plainly.
Your own audio files, public internet radio and podcasts. They live in one focused player, but each gets controls and information that make sense for the way you listen.
Your music, in every detail. Always yours.
