Ardour 3.0 alpha 3 released

Another day, another alpha release. And yes, the URLs do not end in ".bz2" anymore. See below for why ...

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.
  • name changed to 3.0alpha3

Ardour 3.0 alpha 2 released

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

  • "Light" GUI theme now included (no more crashing if you switch to use it)
  • 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.

Recent Purchasing Problems

It appears that PayPal has a bug that started a few weeks ago and is interfering in the smooth completion of the download process for some of our customers. If you run into problems after what you believe was a successful transaction, please point your browser at, enter your invoice ID (not transaction ID) from the your payment confirmation email, and your download will start.

We hope that PayPal will resolve this issue soon. I've amended our order processing system to try to help people when it appears that PayPal's bug has interfered with their transaction.

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.

New features coming in Ardour 3.0

Ardour 3.0 is nearing its first alpha release. As usual, it has been available via SVN for those who want to build it from source during the entire development process, but we are now approaching the point where more user feedback will be useful in finalizing 3.0 before an official release. Below is a (growing) list of new features in 3.0, with links to individual pages that discuss them in more detail.

LinuxDSP Plugins Update

Forwarded from Mr. LinuxDSP ...

As announced recently on the linuxDSP website, the Pro-EQ, Dynamics and Gate plugins have recently been updated. We have recently been doing some work to improve compatibility with different distributions and out of the work done to improve functionality with Meego Linux several usability improvements have been ported back into the mainstream versions of the plugins.

Most notably, the plugin UI windows now open directly under the mouse pointer the first time they are opened, and subsequently remember their last on-screen window position. In Ardour, this means that the plugin UI now opens straight out of the mixer channel.

The plugin bundle includes mono and stereo versions of the Pro-EQ Pro-Dynamics and Pro-Gate plugins. These can provide channel Equalisation, Dynamics processing , Gate, Phase alignment, Switchable High Pass Filter and Gain in each mixer channel.

linuxDSP is one of the few, if not the only full-time commercial plugin developers to support the LV2 standard and these plugins bring DSP processing to Ardour and other compatible DAWs from developers who have over 20 years experience of the pro-audio industry and have previously worked with some of the worlds top pro-audio companies. The plugins can be found here:

An opportunity not to be missed.
