New AATranslator release

I've recommended to quite a few Ardour users that they consider using AATranslator for handling import/export to other session file formats. It is a proprietary Windows application, but it runs well inside Wine and has dedicated and skilled developers who are focused on improving it. It would be lovely if there was an open source tool that did what AATranslator can do, but there isn't, and so I'm happy to run the following "public service annoucement" from the AATranslator team:

Its that time again – another AATranslator release! Read more below for details ....

Ardour 3.0 alpha 5 released

Ardour 3.0 alpha 5 is now available:

After a longer than expected period (alphas will be rolling out every 24-72 hours from now on, I hope), the Ardour team is glad to bring you Ardour 3.0 Alpha 5. This is still an alpha release, but thanks to the amazing and diligent work of Carl Hetherington, has many, many fixes for bugs that surfaced as people have been testing Alpha 4. Read more below for the full list of fixes.

There's also a new feature, not finished as of this release, that allows you to "combine" multiple regions in a track into a single region (and, if necessary, later uncombine them with minimal loss of editing decisions). This is part of a rationalization of the options that Ardour offers for "this sort of thing", and will be completed for Alpha 6.

Changes since alpha 2

  • OSC control now included
  • MIDI binding maps now included (and usable)
  • Package now has an installer, and a README file.
    The installer will put the package into /opt and will attempt to put a link to it on your desktop. The uninstall script (also placed in /opt will remove both the package and the desktop link.

Ardour 3.0 alpha 2 released

A new pair of binary packages of Ardour 3 alpha 2 are now available:

  • Control surfaces now discovered correctly (not yet OSC, that will be in alpha 3)
  • fixed crash when saving MIDI region automation
  • MIDI note display now uses "scientific notation" (
  • a couple of build system improvements and fixes
  • MIDI hardware ports have slightly prettier names (no more alsa_pcm: prefix)

Ardour 3.0 alpha 1 released

We are happy to announce the first alpha release of Ardour 3.0. This is not the final release of 3.0, and its not even a beta release. Please read more below on what to expect from this alpha version.

Plugins, Plugins & More Plugins: Linux DSP MKII Graph-EQ

Announcement from Mr. LinuxDSP: LinuxDSP has recently released the MKII Graph-EQ. This is a significant feature upgrade to the original graphical eq, and not only adds a much improved user interface which shows individual frequency bands in addition to the main EQ curve, but also adds another type of parametric filter which uses innovative DSP processing to provide a de-cramped frequency response similar to analogue EQs.

Plugins offering similar functionality on other platforms can cost as much as $500 and sometimes require extra DSP hardware, which makes this plugin a very cost effective solution. Combine it with the MBC2 multiband compressor to provide a high quality mastering solution. It can be found here:

LV2 IR (Impulse Response) Convolution Reverb Plugin

Tom Szilagyi recently announced a working release of his new LV2 plugin, IR, about which he says "IR is a zero-latency, realtime, high performance signal convolver especially for creating reverb effects. Supports impulse responses with 1, 2 or 4 channels, in any soundfile format supported by libsndfile."

The feature list looks great:
  • Zero-latency convolution of impulse responses with stereo audio
  • Supports Mono, Stereo and 'True Stereo' (4-channel) impulses
  • Realtime operation
  • Very reasonable CPU consumption
  • Maximum impulse length: 1M samples (~22 seconds @ 48kHz)
  • Loads a large number of audio file formats
  • High quality sample rate conversion of impulse responses
  • Stretch control (via high quality SRC in one step integrated with impulse loading)
  • Pre-delay control (0-2000 ms)
  • Stereo width control of input signal & impulse response (0-150%)
  • Envelope alteration with immediate visual feedback: Attack time/percent, Envelope, Length
  • Reverse impulse response
  • Autogain: change impulses without having to adjust 'Wet gain'
  • Impulse response visualization (linear/logarithmic scale, peak & RMS)
  • Easy interface for fast browsing and loading impulse responses
  • Free software released under the GNU GPL v2

More information is available on the IR website. Tom thanked Fons Adriaensen for his work on zita-convolver and Erik de Castro Lopo for both libsndfile and libsamplerate, so we should too.
