What's New
Every major release of Anantar Ultimate, newest first — from the V9 Infinity Player update back to the V4 Precision Playback Engine. Each version builds on the last.
What's New in V9.6
A polish-and-power release — In-App Update, a redesigned Home and Folder view, wireless Wi-Fi Transfer, a new Display settings tool, synced Lyrics, and the iBasso Original Harmonic profile. Available on Discord now; OTA coming soon.
In-App Update
Update the player from inside the app — check for and install new versions directly, no cable or reinstall needed.
Redesigned Home
A rebuilt Home screen — cleaner layout, faster access to recent and favorite music, and a more refined Infinity look throughout.
Redesigned Folder View
The Folder browser is reworked for clearer hierarchy and quicker navigation through large libraries.
Wi-Fi Transfer
Send music to your device over the network — no cable required. Transfer files straight from your computer or phone to the player over Wi-Fi.
Display Settings Tool
A new tool to fine-tune the screen — adjust display behavior to match your environment and viewing preference.
iBasso Original Harmonic
Adds the iBasso Original Harmonic profile alongside the existing Custom Harmonic options, for the authentic iBasso house sound.
Lyrics
Synced lyrics while you listen — load a local offline lyric file or fetch them online automatically.
OverSampling & Interpolation
NOS / OS and Interpolation Rate control now extend to the DX340Max — bringing the full DX340-family DAC tuning to iBasso's flagship.
What's New in V9
The biggest Infinity Player release yet — an on-device DSD Remaster engine, the new Infinity Pure mode, analog-style coloration, Radio Paradise, and a redesigned Now Playing. Available on Discord now; OTA coming soon.
DSD Remaster Engine
Remaster PCM to DSD512 on-device — five DSD Engine modes to tune the character. Supported on DX340, DX340Max, and DX270.
Infinity Pure
Pure Player and native EXT4 unified into one Infinity Pure mode, with a kiosk-style OS experience that keeps the system lock screen.
Analog Coloration
Vinyl, Tube, and Chassis Lover coloration profiles — promoted out of experimental.
Radio Paradise
Built-in Radio Paradise with Block and Live modes, a dynamic multi-channel list, and offline caching of track metadata and artwork.
Bluetooth & USB DAC
A new Bluetooth DAC mode with in-app pairing, plus USB DAC Mode A / Mode B. Paired with a redesigned Now Playing, VU Meter, and Tuning Wizard.
DX340Max Support
Full support for the iBasso DX340Max — feature-identical to the DX340, including DSD Remaster, Analog Coloration, and the complete Infinity DSP suite.
What's New in V8
The biggest leap since launch — native Qobuz hi-res streaming joins Tidal, and NOS / OS DAC modes give you direct control over the interpolation filter. And for the first time, DX270 is fully supported alongside DX340 & DX340Max.
Native Qobuz Integration
Studio-quality FLAC up to 24-bit / 192 kHz, streamed bit-perfect through the iBasso Native Driver alongside Tidal. No transcoding, no Android resampling — the file Qobuz serves is exactly the file your DAC plays.
NOS / OS DAC Modes
Switch the DAC's interpolation filter in real time. NOS (Non-Oversampling) for the raw, direct character. OS (Oversampling) for the smooth, reference sound. Both are bit-perfect to the file — the choice is preference, not fidelity.
Interpolation Rate
Three voicings on the CT7302 — Smooth (2×, warm and analog-leaning), Balanced (4×, natural and detailed), and Detailed (8×, crisp and airy, the iBasso default). All bit-perfect to the file. DX340 & DX340Max only.
DX270 Support
Anantar Ultimate now extends the core audio optimization stack to the iBasso DX270 — EXT4 support, kernel boot profiles, the library, Qobuz and Tidal, and the complete Infinity Player experience. One module, every flagship.
What's New in V7
The most ambitious update yet — a brand-new Infinity Player, advanced PowerScope, Salon Stage, faster system-wide performance, and more.
Anantar PowerScope
Built exclusively for DX340 & DX340Max + Anantar Ultimate. Reads directly from the I2C bus, fuel gauge chips, and Linux sysfs — surfacing hardware data that no stock app ever exposes.
Infinity Stage
A new fifth soundstage profile between Theatre and Chamber — refined, intimate, yet open. Perfect for vocal and acoustic recordings.
Faster App Loading
All apps launch noticeably faster system-wide via pre-compiled package optimization applied automatically during installation.
Infinity Player
A cutting-edge companion music player designed exclusively to interface seamlessly with Anantar Ultimate for bit-perfect playback.
Introducing: Infinity Stage
The highlight of V5 is the Infinity Stage. We've implemented a new configuration for how the system handles heap memory to unlock a much larger, more immersive soundstage. We've included four distinct profiles:
Studio
Clinical precision. Tight, punchy bass and zero reverb. It's very "honest" and precise—perfect for hearing every micro-detail without any coloring.
Chamber
Personal Favorite. Enhanced stereo width and airy separation that feels like a natural, open room. Wider stage but remains completely realistic.
Theatre
Grand-scale immersion. Rich ambient reverb for a vast, cinematic experience. Works incredibly well with orchestral or live tracks.
Original
For the purists. Keeps the authentic V4 sound signature you know and love, maintaining a natural balance of space and detail.
🧠 Under the Hood: Improved CPU Pinning
Deep system scheduling refinement to optimize hardware interaction.
- Reduced Context Switching: App runs steadily on specific cores, preventing the CPU from jumping between tasks.
- Clearer & Cleaner Sound: Noticeably more stable audio delivery with a "black background" improvement.
- Effortless Listening: The whole experience feels more robust and technically refined.
What's New in V4
The most comprehensive release yet — precision playback, battery intelligence, and a brand-new notification system.
Precision Playback Engine
- Direct Data Path (I/O Optimization): Streamlines data flow from storage to CPU cache — removes unnecessary processing layers, significantly reducing latency and CPU overhead.
- Reduce Jitter: Linear scheduling approach prevents micro-stutters, ensuring a perfectly stable data stream for high-bitrate playback.
- I/O Interrupt Affinity Tuning: Pinpoints interrupt requests between storage controller and audio engine to specific CPU cores — reduces latency spikes during demanding playback.
- LocalPlay Engine Optimization: Fine-tuned CPU scaling governor for local playback, balancing power delivery with signal stability.
- Automated Background Terminator: New intelligent service identifies and suspends non-essential tasks during playback, freeing system resources.
DeepSleep V2 Enhancements
- DeepSleep Stats: Cumulative sleep duration and real-time battery discharge rate notifications.
- Big Core Management: Automatically deactivates BIG cores when DeepSleep is triggered.
- Instant Recovery (CPU Boost): 60-second MAX CPU Boost triggers immediately on restore from DeepSleep.
- Native Doze Integration: Deep-level integration with Android's Doze, instructing the low-level OS into more effective deep sleep states.
- Battery Longevity & Guard: Stricter Play Store background restrictions to prevent idle battery drain.
Enhanced UX/UI (Notification System)
- Native Integration: Fully migrated from Magisk-based app overlays to Android Native Notification framework for improved stability.
- Refined Messaging: All notifications rewritten with clearer, more intuitive language.
- Bubble Notifications: Multitasking-friendly bubbles for quick access to essential controls.
- Initial Anantar App Release: Official portal to the Anantar Ultimate site — a unified hub for community updates.
🐛 Bug Fixes & Compatibility
- Software Validation: Extensively tested with UAPP, Neutron Music Player, and Nova Launcher.
- Note on Neutron CPU DSP: PCM-to-DSD real-time conversion in Neutron is supported but increases CPU load and thermal output significantly.
- MicroSD EXT4 Fix: Fixed a critical bug in the microSD cleanup process for ext4 partitions.
- iBasso Firmware Updater Fix: Resolved an issue where the updater failed to launch in the optimized environment.
