  • OCA´s Audyssey ONE "NEXUS"

    A1 Evo Nexus v2.9 (03 Nov 2024)

    • Target level bug required a re-fix and is now robust.

    • When “force small speaker” or “force weak receiver” options are used, Nexus will no

    longer evaluate LFE and LFE + Main options for front channels and finalize

    optimization quicker.

    A1 Evo Nexus v2.8 (03 Nov 2024)

    • A minor bug in REW caused inaccurate target level calculations and the functions for

    speaker/sub volume alignment needed to be revised to fix that.

    • Don’t forget to download and try the latest “Target Curve Nexus” in Popular target

    curves” folder.

    • NO OTHER CHANGE from v2.7!

    A1 Evo Nexus v2.7 (26 Oct 2024)

    •

    Systems with Dolby speakers were being affected from 0m speaker distance settings in “REW Measurement mode” files so v2.7 measurement mode files will set all distances to 2.75m

    •

    Consequently, Dolby enabled speaker distance settings will be improved in the optimized calibration files so repeat measurements for those of you with Dolby enabled speakers is advisable.

    NO OTHER CHANGE from v2.6!

    BETA

    Dirac Live Beta 3.11 // 2024-10-25

    Changes listed are relative to the latest public stable release.

    Features

    • Delay alignment update: The delay compensation for speaker distance alignment has previously been slightly confusing in that the shown delay values have not corresponded exactly to the measured acoustic delay. This has been due to that part of the delay alignment was included as a pre-amble of zeros in the Dirac Live filter itself, leaving only the remaining part of the alignment to be applied outside of the Dirac Live filter. A consequence of this partitioning was that if the user manually disabled the delay alignment, then the part of the delay inside the Dirac Live filters would remain being applied, resulting in a misalignment of the speakers.
    • Target curve update: We’re unifying how the advanced target curves (breakpoint) and simple target curves (high and low shelves) behave as input to the filter design. Under the hood, shelving targets will now be converted to breakpoint targets and follow a same filter design process.
    • We’re introducing improvements in our measurement functionality:
    1. Microphone recording level: Different microphones have resulted in different recording levels between MacOS and Windows due to different gains being applied on the microphone hardware and on the OS (operating system). For example, the UMIK-1 with USB-C connector has experienced very low recording levels on MacOS. In order to make all microphones work on all OS:s, we’re now only applying gain adjustment within the Dirac Live application.
    2. Improved error detection on all platforms: An improved algorithm for detection of missing samples in the measurement recording is introduced. This will generate significantly less false alarms about measurements being “imprecise” (showing an exclamation mark). The improved algorithm will always be applied, both when using microphones connected to the AVR/receiver device and to the PC/Mac.
    3. Improved recording quality on Windows: The Windows WASAPI driver will be used in Exclusive Mode by default. Exclusive Mode significantly reduces the probability for losing samples during the recording. It is possible to opt-out of Exclusive Mode by setting the environment variable: DAUDIO_WASAPI_NON_EXCLUSIVE = ON
    • We’ve extended the local logging from the Dirac Live, including received notifications from the connected device, to improve problem traceability.

    Bug fixes

    • We have fixed an issue that caused the mic gain slider to sometimes not being shown in the Volume Calibration page.
    • Sometimes, a persistent error, such as an unreachable network, could generate multiple error messages. We now avoid generating identical generic error messages.

    Known issues

    • Filter export to devices from Onkyo/Integra/Pioneer take longer time than usual, but it eventually completes.
    • It is not possible to use the maintenancetool to uninstall the Dirac Live application on Intel-based Macs running MacOS 15.

    Workaround 1: It is possible to install a newer version of Dirac Live without first uninstalling.

    Workaround 2: It is possible to uninstall by dragging the application to the trash can.

  • OCA´s Audyssey ONE "NEXUS"

    A1 Evo Nexus v2.6 (22 Oct 2024) Optimized for REW Beta 57 and above!

    •

    Fixed: Incorrect inverted sub prompts during crossover searches

    •

    Improved: Dip efficiency calculation during target curve tracking

    •

    Slightly extended crossover search frequencies as sometimes an unexpectedly higher frequency can help with the dips. Limiting them with script customization is always possible.

  • OCA´s Audyssey ONE "NEXUS"

    A1 Evo Nexus v2.3 (17 Oct 2024)

    Optimized for REW Beta 57 and above!

    • Enhanced Volume Input for Dynamic EQ Measurements

    Introduced a user-friendly interface to input AV Receiver volume levels when REW

    measurements are taken with Dynamic EQ on.

    • New Dynamic EQ Surround Boost Compensation Tool

    The fixDynamicEQ.exe tool (currently Windows only) has been finalized. When run

    from a PC on the same network as your AVR, it automatically:

    o Detects your AVR and reads the volume level (stored in the title) along with

    all initial speaker levels from your final calibration file.

    o Continuously adjusts excessive surround and height speaker boosts in real

    time based on an optimized formula.

    o Note: Place fixDynamicEQ.exe in the same folder as your calibration file for

    seamless operation.


    • Precision Compensation for Dynamic EQ in REW Measurements

    REW measurements are now precisely compensated for the high-frequency boosts

    caused by Dynamic EQ in the uncorrected region. This ensures greater accuracy in

    REW and in your final filters, adjusting based on the exact volume level during

    measurement.

    • Improved Dolby Speaker Handling

    Enhanced handling of Dolby speakers for optimized performance.

    • New Chime Alerts at Key Stages

    o A notification chime sounds when the Dynamic EQ prompt appears, helpful if

    you've started optimization and stepped away.

    o A distinct tone signals the end of optimization, adding convenience for those

    running optimization remotely.

    • Minor UI Enhancements and Bug Fixes

    A1 Evo Nexus v2.2 (15 Oct 2024)

    • Fixed a bug shifting target level prematurely.

    Atmos REW sweeps update 07 Oct 2024 (Final update)

    •

    The issues with Atmos sweeps (lossy and lossless) have all been fixed. Both sets of sweeps only play their respective channel with all other channels completely muted, they all have -20dB internal level (same as Blu-ray masters for a more realistic target curve), NO dialnorm settings (but turn off loudness management regardless – better safe than sorry), 10sec initial silence - so you can leave the room if you want to before the sweep starts. If you can play lossless sweeps in your system, measure everything including subs with them. If you need to use lossy (.mp4) sweeps (i.e. you are a Mac user), you should use REW’s internal sweep (with the settings shown below) for subwoofer measurements to avoid your sub response being filtered beyond 120Hz. Every other way, the lossless and lossy sweeps are acoustically identical.

    •

    Please note that multiple subwoofers should be manually isolated during each subwoofer (SW1, SW2, SW3 or SW4) measurement.

  • OCA´s Audyssey ONE "NEXUS"

    v1.10 - 06 Oct 2024

    •

    Fixed some final optimized calibration files containing multiple subwoofers not loading in the MultEQ.

    v1.9 - 06 Oct 2024

    •

    Resolved a volume alignment issue in systems with 3 or more subwoofers.

    •

    Corrected a misleading “invert each of your subs” prompt.

    •

    LFE + Main mode double bass evaluation is extended to include speakers with 60Hz natural roll offs.

    •

    Implemented an “OCA” favicon to Nexus tab in the web browser tab for easier navigation and quick identification

    •

    Temporarily removed lossless Atmos sweeps due to a problem which can cause same side top speakers playing simultaneously. Please use provided Atmos DD+ (.mp4) sweeps until the problem is fixed. Since LFE (subwoofer) channel sweeps is hardcoded by Dolby with a 120Hz lowpass filter, it’s not provided in the folder. You should use REW’s own sweeps for subwoofer measurements.

    • Required REW measurement settings for the subwoofer channels are as below (highlighted yellow):

  • OCA´s Audyssey ONE "NEXUS"

    v1.8 - 05 Oct 2024

    • Fixed a bug where a warning for exceeded volume limits during Audyssey auto-levelling compensation

    was not working as intended and added required volume offset information in such warnings to help

    with repeating measurements.

    • A reminder was added at the end of the optimization process to verify Dynamic EQ settings on the

    AVR after transferring the final calibration.

    • Dolby Atmos TrueHD.subwoofer sweeps (SW1.mlp, SW2,.mlp, SW3.mlp, SW4.mlp) were replaced in

    the zipped folder because of an embedded lowpass filter @120Hz in them. Please note that .mp4

    sweeps for subs already have that filter and you should use REW’s internal sweeps for subwoofer

    channels if you cannot play .mlp files in your computer with the following settings

  • OCA´s Audyssey ONE "NEXUS"

    v1.7 - 04 Oct 2024

    • Fixed: Trademark could still float over the progress log in some web browsers

    • Fixed: Subwoofer level was not raised correctly before producing final EQ filters for small speakers.

    • Added: A customization option within the script for enabling low-shelf filters for DIY subwoofers

    (option can only be adjusted inside the script).

    Important note: All Dolby Atmos “play from file” sweeps for REW were replaced today with different

    subwoofer sweep level encoding eliminating the need to use -10dB volume offset for subwoofer

    measurements. Please use these sweeps in all your future measurements

    Dirac Live 3.10.10 Software Changelog

    Features

    • None

    Bug fixes

    • Fixed an issue where the new measurement qualification algorithm was not taking into account the audio device driver’s flagging and counting of recording discontinuities. The potential effect for users updating from 3.10.3 is that measurements that were previously approved could now be marked as imprecise (with the exclamation mark). However, this will only affect a small subset of users having tested this new measurement qualification functionality.
    • Fixed an issue where Dirac Live 3.10.3 could not be installed on MacOS 12 or older. It now installs on MacOS versions back to 10.14.
    • Fixed a problem in Volume Calibration where the stimuli gain could be reset to maximum instead of 0dB.
    • Fixed a problem on MacOS where window size and position was not remembered between sessions.

    Known issues

    • Filter export to devices from Onkyo/Integra/Pioneer take longer time than usual, but it eventually completes.
    • It is not possible to use the Qt installer maintenancetool to uninstall the Dirac Live application on Intel-based Macs running MacOS 15.
      Workaround: It is possible to install a newer version of Dirac Live without first uninstalling.

    v1.3 - 02 Oct 2024

    • Fixed an issue where selecting an optimization option did not convert directional bass

    mode to standard bass mode.

    • Resolved a problem where the calculated subwoofer volume could exceed AVR limits

    in extreme cases.

    • Corrected the error handling so that the "Unable to detect REW measurements" error

    does not appear when other measurement matching errors are present.

    • Slowed down Nexus slightly, as a few users reported unexplained errors with their

    REW setups.
