Vocoder

I thought these graphs were already up here.

Well, here’s some 16 band vocoder Graphs.

These are patched to be on a stereo Aux, so you can send whatever you want to them, but work still with a mono strip.  Still, I invite you to dig in and make sure you see how it’s working, and to get it sounding how you want.  For eg. the envelope times are sort of slow, as well when used on a stereo stip it’s pseudo-stereo, panning some bands more on one side or the other, so for mono use you’ll want to figure that out

MIO Console 5.3 new SIMD mixer

I inquired on the mailing list what the benefits were of the new SIMD mixer in the just released 5.3 version of MIO Console. Since I can imagine that this interests quite a lot of users, I took the liberty to re-publish the respons of B.J. Buchalter:

We re-implemented the mixer and metering routines for the 2d Card to utilize the SIMD extensions in the SHARC processor. This allows us to process two cross-points in the mixer (and two meters) with the same number of instructions that one used to take. Not all of the mixer could be optimized with SIMD due to limitations in the instruction and data architecture, but the net effect of the optimization is to reduce the DSP load used by the mixer and metering routines. The actual improvement is dependent on the size of the mix busses you are using — busses with more input channels get a bigger improvement in DSP utilization as more of the time is spent processing cross-points than in the setup code that is not parallelizable. Full width mixers (32 channels) achieve a reduction in DSP usage that is around 40% or so IIRC.

The reduction in DSP usage for hardware metering essentially increases the amount of DSP available for mixing and plugins as that processing always occurs. I don’t remember what the improvement was off the top of my head, but I think it approached 30% or so (but don’t hold me to it). The metering did not amount to a large amount of baseline DSP usage, but every little bit helps!

Thanks a lot for the continuous improvements over the years B.J, Metric Halo is really true to its future-proof statement.

MIO Console 5.3 is available

Metric Halo released version 5.3 of MIO Console today. As usual it’s a free upgrade for existing users and its sports a number of interesting fixes and improvements. Here are the release notes:

Major new features include:

  • New 64-bit AU version of the ConsoleConnect plugin for seamless compatibility with 64-bit hosts (including Logic).
  • Addition of sidechain routing within the Mobile I/O mixer for plugins that support sidechain input.
  • Full support for setting all BEXT metadata when recording BWF files
  • Support for long filenames in the Record Panel
  • Rewritten and reorganized documentation
  • Propagation of mixer strip colors to EuCon control surfaces
  • Support for the LIO-8
  • New SIMD mixer for reduced DSP usage (effectively provides more DSP power)

Usability Enhancements include:

  • Document proxy in the window title bar
  • Hierarchical menu for plug ins in Graph windows
  • Addition of bypass support for a number of plug ins
  • Mixer templates for LIO-8
  • Addition of new keyboard modifiers to accelerate some operations
  • Improved cueing speed in RP playback
  • Improved synchronization of Front Panel and MIO Console calibration
  • Removed latency jitter on driver start to provide consistent roundtrip transport latency

The update also includes fixes for more than 50 potential issues discovered in older versions of the software.

Stefan Bahr from Metric Halo Germany at Musikmesse

While being at Musikmesse I had the great pleasure to meet Stefan Bahr from Metric Halo Germany in person.

He was kind enough to provide a five minute overview of the product line and some of the advantages of each audio interface, including the new LIO-8!

Strong endorsement for Metric Halo in ProSound News

Ed Abbott, technical engineer and R&D specialist with Universal Mastering Studios talks about how his restoration and archival services for the company’s vault rely largely on Metric Halo ULN-8 and ULN-2 devices. He also talks about the power of the DSP and SpectraFoo.

A great article to make to believers feel better and to make it easier to convince those that are reluctant :-)

How to contribute to MIOZone video tutorial

Several people have contacted me privately asked for more information about how to contribute to MIOZone. Those that already received editor access also felt a bit lost in the administration interface. To make all this easier to understand I recorded a tutorial video about this.

You can see it here:
http://miozone.org/how-to-contribute/

I hope this makes things clearer and motivates you to start contributing information to MIOZone.

Monitors, level and pads

Near field monitors like to see monitor level audio signals, which is roughly 30 dB down from line level. This means that the outputs of our MIOs have to be turned down significantly to make the monitors happy.

This is no problem on the ULN-8 since it has an analog domain volume control that goes all the way down to mute, however this is not the case for the 2882.

When the 2882’s outputs are ran hotter, they sound better. In this case, it’s generally recommended to get a pair of inline balanced pads to put in between the 2882’s outputs and the near field monitors, and then run the 2882 at full-scale output level.

These are some pads that have been recommended on the MobileIO mailing list:

Another option seems to be to build your own attenuators by placing high-quality resistors inside a balanced cable connector, or you can build your own pads: http://www.uneeda-audio.com/pads/

New graphs download section

To make it easier to find graphs that have been contributed to MIOZone, I’ve created a dedicated page that contains a list of all graphs that are available for download here.

How to install custom graphs

If you have a +DSP license for your Mobile I/O, you can build your own DSP graphs or use pre-built ones to get instant results.

This is how you install them:

  • unzip the downloaded graph archive
  • open Library/Preferences/MIOPlugInPresets/Graphs/ in the finder, starting from your home
  • create a dedicated directory there for custom graphs, for instance Library/Preferences/MIOPlugInPresets/Graphs/MIOZone (this is not really needed, but it’s a good idea to keep these separate for maintenance)
  • move the unzipped graph file into that directory
  • restart your MIO Console
  • open a graph window and you’ll find the new graphs in the pop-up menu next to the ‘patches’ label where it says ‘Factory Default’ (see screenshot below)
