bit Drive 3.0
Powerful. Intelligent. Effortless.
bit Drive 3.0 marks a major evolution in DSP software, bringing professionals and enthusiasts closer than ever to fast, reliable, high-quality sound tuning. With new advanced tools and performance improvements across the board, version 3.0 sets a new benchmark for installation speed, tuning precision, and OEM integration.
Powerful Tuning, Made Effortless.
It is the heart of bit Drive 3.0 — the intelligent, fully automated tuning engine that has been completely re-engineered to deliver outstanding results in the most challenging installation conditions and with any type of audio system. It precisely configures time delays, output EQ, and speaker levels with even greater accuracy, so you enjoy cleaner, more dynamic sound with less manual intervention.
IMPROVED SYSTEM LOUDNESS
Accordo 2.0 is now even more powerful on tuning EQ and levels for each speaker while ensuring a maximum undistorted volume for your system. The result is a fuller, powerful soundstage with a proper balance between all components.
IMPROVED PRECISION AND RELIABILITY
ACCORDO 2.0 adds to the routine a preliminary measurement of the environment background noise, and adjusts the test signal level for each speaker in real-time to get a proper SNR and avoid clipping issues. This process is fully automatic and gives you an incredibly repeatable and precise tuning.
Enhanced Microphone & Interface Compatibility
ACCORDO 2.0 now pairs effortlessly with today’s most popular measurement microphones and the USB analog audio interfaces you already use—just plug in, hit measure, and capture accurate data without extra adapters or driver tweaks.
Improved time delay detection
ACCORDO 2.0’s delay-correction engine now pinpoints arrival times with even finer resolution, ensuring perfect alignment across demanding setups—high-power subwoofers, rear-deck surround speakers, under-seat woofers, and more. The result is a phase-coherent stage that remains consistently accurate and repeatable, every single measurement.
The intuitive calibration wizard leads you step-by-step, while the redesigned interface delivers live visual feedback that locks in the optimal signal level—letting even first-time users achieve reference-grade tuning. Thanks to its streamlined, single-pass analysis, the process flags any sub-optimal conditions with clear warnings yet still delivers an excellent, repeatable result every time.
The left and right surround outputs are now signal duplicates, optimizing DSP resources.
- Improved vocal intelligibility
- Dynamic adaptation to music content
- Optimized DSP resource usage
- Seamless integration with OEM stereo systems
UPMIXER 2.0:
Dynamic Center, Cleaner Soundstage
is the perfect tool for systems using stereo sources but requiring a center channel to enhance front-stage focus ambiance.
This new version introduces four presets to suit different listening environments:
- High: enhances vocal clarity with a more pronounced center
- Medium: balanced stereo with natural center
- Low: preserves a broad stereo image
- Dynamic: adapts in real-time to the correlation between left and right channels, increasing center gain when appropriate and reducing it when spatial separation is needed
INPUT EQ 2.0:
De-EQ Modern OEM Premium Systems
As OEM audio systems become more complex, bit Drive 3.0 provides the tools needed to tame them: premium OEM systems often use asymmetrical crossovers and multiple all-pass filters in the transition bands, leading to out-of-phase conditions at specific frequencies.
bit Drive 3.0 solves this with:
- High-Pass Filter (HPF) available on Input EQ Band 1
- Low-Pass Filter (LPF) available on Band 12
A single EQ band can now correct an entire crossover slope, freeing up EQ resources and improving phase accuracy.
This enhancement makes bit Drive the go-to solution for OEM integration specialists dealing with de-EQ of factory audio signals.
UPDATE CENTER:
One Click to Stay Up to Date
bit Drive 3.0 introduces the Update Center, a fully integrated panel for managing firmware and software upgrades without ever leaving the software.
Now you can:
- Download and install updates for bit Drive, AF bit, AF M1.7 bit, DRC AC, and DRC MP CAN
- Avoid visiting external sites or running standalone updaters
- Automatically reload your saved setup file after updates (if previously saved)
Say goodbye to update file downloads and restarts. The entire process is handled inside bit Drive for maximum convenience and minimum disruption.
Compatibility & Access
bit Drive 3.0 is compatible with all Audison Forza bit DSP amplifiers and supported DRC interfaces. The update is available as a free download for existing bit Drive users.
Built for Installers, Designed for Audiophiles
Whether you’re commissioning a full-stage system, upgrading factory audio, or integrating with complex OEM networks, bit Drive 3.0 is your trusted platform. It’s the result of real-world feedback, technical innovation, and our commitment to delivering the most intelligent DSP interface in car audio.

bit Drive v3.0 Release notes:
Accordo raises a new level of performances in setting automatically the time delays, the output EQ and levels.
The final result is even better than Accordo 1.0:
- The general volume is now much louder;
- The subwoofer volume remains louder and better aligned with Front and Rear speakers;
- The system level calibration is now automated in order to simplify the user job and ensure a proper SNR for the microphone in use;
- The system level calibration has been improved to be compatible even with USB microphone with low gains or no gain options at all;
- The Accordo measurements and calculations have been strengthened to overcome background noise interferences and to perform well even in systems with very powerful subwoofers.
- The new Update Center integrated in the bitDrive software can manage both firmware and software upgrades entirely within bitDrive itself.
- In the Update Center you can directly download and install software and fw upgrades, both for the dsp amplifier and DRC AC or DRC MP CAN (if they are being used).
- No need anymore to download any upgrade file from Audison website, no need anymore to close bitDrive when doing these upgrades.
- At the end of each upgrade operation, bitDrive sw can restart automatically and reload your setup file (if you saved it in advance), thus speeding up the tuning operations.
- Added “Dynamic” option to adapt in real-time the Center speaker level according to the Left & Right correlation on audio tracks.
- With many premium systems today from Bose and Harman, the OEM signals have asymmetrical crossovers with a wide transition band, which is something very uncommon until few years ago. These leads to phase misalignments at certain frequencies which require many all-pass filters in the input EQ. Sometimes the allpass filters are not enough, or they force the user to run out of EQ bands to correct the entire OEM signal.
- we add the Lowpass and Highpass filter option to input EQ bands #1 and #12 (as we did already for the Output EQ bands 1 and 15). In this way one single EQ band can defeat the entire range of frequencies instead of using many allpass filters and run out of EQ bands
- this makes the input signal correction much easier in bitDrive with OEM Premium systems
