Ardour source repository moves to git

The official repository for Ardour source code has now moved to git instead of svn. It is hosted at Users without write access can clone it using git clone git:// Users with write access have been privately notified of the changes.

We will likely clone the repo at github or a similar site, and keep it automatically up to date.

Release Plans for Ardour 3.0

A decision has finally been made regarding the release of Ardour 3.0. First, some general stuff.

Subversion change (for those with write access)

Our website host has changed the "host key" used to identify the machine we know and love as Existing attempts to access the SVN repository with write access will fail. To fix this, remove from your ~/.ssh/known_hosts file, and the next time you attempt to connect to the SVN repository just answer the questions in the affirmative.

For the justifiably paranoid among us, the new RSA key is: 96:91:a5:2f:18:a7:56:55:b3:75:23:49:74:bc:22:e2

Slow GUI issues with binaries: resolved

Several people have reported "slow GUI" issues with prebuilt versions of Ardour from when used on Linux systems with Nvidia video interfaces.

Issues with Subscriptions (Fixed)

There have been issues in recent months with people subscribing (providing a monthly payment of US$1, US$4 or US$10 to help support continued development of Ardour). The problem was discovered today - the module we use to track subscription payments assumes the use of a single PayPal account, but in order to utilize PayPal's micropayments option, uses two different accounts with PayPal. It didn't prevent subscriptions from working, but did not know about them. This has affected all new subscriptions since I started using the micropayments system a few months ago.

The issue is now fixed, and I'm working with everyone affected by it to get them correctly registered on

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 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.

Harrison Mixbus is now available for Linux and OS X

Great news from Harrison Consoles .... and yes, for those who are curious, your purchase of Mixbus does generate some income for Ardour.

Mixbus™ is a full-featured Digital Audio Workstation (DAW) with "True Analog Mixing"™: a combination of Harrison's world-renowned sound and features in a knob-per-function interface. Now cross-platform on both Linux and OSX, Mixbus provides a solution for engineers and mixers who need a recorder, editor and mixing system with world-class sound and features.

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.
