New in DSP PC-Tool 5.00.02 Beta (May 26, 2022)

  • TuneEQ:
  • One of the major new things in DSP PC-Tool 5 is our new proprietary TuneEQ function. This integrated automatic tuning mode provides a new way to automatically adjust your virtual or output equalizers. It utilizes a single spatial averaged measurement with at least 1/6 octave resolution to simulate and evaluate the best possible parameter set for your equalizer to achieve a specific frequency response target. The target itself can be freely designed as a Reference Curve.
  • TuneEQ is an extremely flexible but simple to use function which will use any given number of equalizer bands to perform a frequency response correction by utilizing the full possibilities of parametric equalizer bands. It will use the full function set of the parametric equalizer including the center frequency, Q-factor and gain adjustment.
  • One of the major design aspects of this function was to make its usability as simple as possible while the complex processes are done automatically in the background.

New in DSP PC-Tool 4.72a (Oct 8, 2020)

  • ATM - This software version contains the first official release of our proprietary "Automatic Time Measurement" function. Since the first beta test version, the ATM has been continiously improved and enhanced to ensure its operability on most of all applications. The ATM offers now the option to select different input sources (e.g. Digital Input or Extension Card input) for non-VCP devices to enable a measurement through all possible inputs of the DSP. In addition a result page has been added after the measurement process which allows the comparison of the time alignment adjustment 'before' and 'after' the ATM process. The result page will also offer detailed guidance and assistance if a measurement failed. The whole menu has also be updated by several explanations and the ATM function can now be directly started in the Time window
  • DCM - A new function called "Device Monitor" has been added. The device monitor is available for all ACO platform enabled products and shows live temperature data within an adjustable time frame as a graph and min/max values. For some specific DSP amplifiers (needs to be equipped with a "Regulated Power Supply" & the "ACO platform" - currently HELIX V EIGHT DSP, HELIX V TWELVE DSP, MATCH M 5DSP MK2) an input voltage monitor is also available which allows to check the stability of the input voltage especially during operation.

Thereby the connection between the computer and the DSP, the saving, loading and changing of sound setups as well as the complete update process of the device is getting much easier and faster than before. In addition each DSP which incorporates the new ACO platform is equipped with a new flash memory for storing up to 10 sound setups internally. Those sound setups can now be switched within milliseconds and editied without closing the software. In addition there are several new functions which can be found in the new "ACO Features" tab in the DCM menu.
  • The FX-Menu, which will be available for all devices which incorporate the new ACO plattform, has been optimized for the universal use of our unique DSP algorythms to configure them more in detail.
  • Main - a new function called "Notes" has been implemented which allows to store short comments about the actual sound setup. Those notes will be saved in the sound setup file (afpx) and as well as in the internal memory of the DSP. Therefore the number of characters of this function has been limited to 500 for now. You will find this function by clicking on the note symbol beside the sound setup name.
  • MATCH UP 7BMW - an issue with the optical input has been fixed. Therefore an update of the DSP operating system will be necessary. Please save your DSP adjustments in advance on your laptop.
  • Several small optimizations and bug fixes
  • The Sound Setup Menu (click on the setup name) has been extended when connecting to an ACO device:

  • New main menu button called FX has been implemented to configure the new DSP features of the UP 7BMW amplifier:
  • Augmented Bass Processing
  • Contains the "Dynamic Bass Enhancement" algorythm and the "SubXpander". The Dynamic Bass Enhancement extends and boosts the deep bass response depending on the listening volume and the music signal. The lower the listening volume and/or the low frequency proportion in the music signal is the more our algorythm is working to optimize the bass reproduction. The SubXpander is a separate function which adds subharmonic tones to the fundamental bass for an ultra-deep bass experience.
  • Center Processing
  • Contains our proprietary "RealCenter" algorythm, which emphasizes the monaural information of the left and right stereo signal and dynamically processes and reproduce a center signal. As a result a unique staging for the driver and passender seat can be achieved at the same time. The ClarityXpander is a separate function which statically or dynamically improves the high ferquency response to create crisp and clear brightness on the center channel.
  • Front Processing
  • Contains our proprietary "StageXpander" algorythm which enlarges the sound stage provided by the left and right side speakers to achieve a wider stereo panorama. The ClarityXpander is also available on these channels as a static function to create a crisp and clear brightness as well on the side speakers.
