Isadora Experiments – Triggering and manipulating audio from live video

Recently I’ve had the chance to experiment with Isadora by Troikatronix in using live video to trigger and manipulate audio for use in performing arts performance for triggering multiple sounds from multiple cameras. The intenton is to either use dancers or simply members of the public in the exhibition to trigger audio from their movements.

Isadora Audio Trigger From Stream Patch

The following patch you can see takes use of several “actors” available in Isadora to route a single camera signal (video in watcher) and analyse it (eyes).

Of the many parameters you can watch using eyes the main ones I’ve used include “hit column” and “hit row” for simply tracking a the main object of any given frame of live streamed video. Corelating these to a grid gives a numbered intersection I’ve been able to use to trigger other sounds.

However smoothening this every changing series of digits is essential as to not give off hug he fluctuations in values and subsequently triggered audio.

Passing after this section the final state involves setting several “inside range” actors to watch for separate bandwidths of values at different ranges. Thus enabling me to trigger sounds for objects generally high. low, left or right of live streamed shot. This passes each of these ranges through to separate audio file triggers which are enabled when the value reaches that between the values set by the actor “inside range”.

Further exploration of manipulation can be seen with using “obj size” in eyes to manipulate the volume of the triggered sounds via the size of the object tracked on screen. Like wise the objects vertical position has been used to govern the speed at which the triggered audio is played.

All in all this has led to some very experimental soundscapes to be utilised live during a performing arts event here in Birmingham. See below for a video of one of the first experiments in using an in built webcam to provide the streaming video content to trigger the samples. More developments soon!

Birmingham Town Hall – Tony Christie

I’ve been privileged enough the past few weeks to attend two or Birmingham’s greatest and most renowned venues. Town Hall and Symphony Hall.

Please see below for photos of the Town Hall photos of Tony Christie’s sound checking using the Soundcraft Vi1 console. What a privilege.

Pro Tools 310i at Alchemea with Justin Fraser

The Pro Tools 310i

Wow! What a 3 days it’s been attending the Avid Pro Tools 310i course @alchemeacollege London.

I’ve been so privileged to learn advanced icon techniques from Justin Fraser whose worked with such artists as: Seal, Art of noise, Peter Gabriel, Genesis, Charlotte Church, The Frames and Tracy Bonham for whom he received a grammy nomination in 2002. His live portfolio also includes such as established acts such as Christina Aguilera and U2 to name only a few.

To say the least I’m now fully mind blown as to the capabilities of the icon setup and can now hopefully pass on this knowledge on to students at BOA and into our mixes.

Here is some snaps from alchemea:

BOA Big write #BOAwrite “SinderHella”: World book day

BOA Big Write Lawrence Harvey

BOA Big Write Lawrence Harvey

To celebrate world book day we decided to use twitter to help write a story across BOA. Using account @BOA_Lit tweeting stories with #BOAwrite to collate tweets and display a finished story via @BOA_Lit and on the BOA Blog.

The project involved projections of twitterfall and of a movie inspired by books that have been made into films! The event was a great success with an in depth blog viewable here. It turned out to be a dark Cinderella style tale we named “Sinderhella”.

I even got in the post pic by complete accident!

Do they know it’s Christmas cover: Pro Tools HD

Before the Christmas break I was lucky enough to record, mix and master a cover of Band Aid: Do they know it’s Christmas using a pro Tools HD 3 rig and D Command 40 fader console!

The main recording setup labelled “Group vocal recording” shows the utilisation of two AKG c414 XLS’s in a spaced pair for close micing and a pair of AKG C451b’s in a Coincident-XY position to add ambience to the small ensemble recordings. The aim was to record vocals of as many students as possible to contribute to the Christmas project and ended up using 97 audio tracks, 3 auxiliary tracks, a click track and a master fader.

Standard “solo” arrangements for the song shown in “Double tracking eq compression” made use of Waves C1 compression and 4/7 band EQ to control the vocals tonally. The D Commands central control section allowed for easy and quick maipulation of these controls as displayed in picture “D Command EQ and Compression controls”. The rotary encoders for EQ and compression and subsequent paging controls allowed for full control of the plugins and easy adaptation to individual channels.

The solo sections we’re typically double tracked to add depth to the vocal sound often utalising extra send attenuation via D Command flip controls to parallel compression and reverb buses. The picture entitled “Pro Tools HD Edit Window” displays the use of multiple takes via the room mics (Stereo XY AKG C451b’s) to give the vocals that large choir effect towards the end of the song.

Photos :Submaster Reverb and Para Comp Auxs”, “Pro Tools HD Plugins 2” , “Bus setup window” display the extensive use of auxilary effect processing in the track. Using the D Command flip control the channel sends could be adjusted from the main fader controls to allow quick assignment of channel levels into parallel compression and reverb sends. Avid/Digidesign’s Impact bus compression plugin was used for parallel compression to the vocals and in particular to double tracked elements to allow great control of the effect in the whole mix. Similarly “Revibe” was used for the reverb send with detail representations of a warm church utilised to add a more live feel and blend the performance of seperatly recorded takes together in natural sounding and controllable ambience.

Finally “Pro Tools HD System Useage” and “Pro Tools HD Plugins 1” show the massive amount of TDM’s used to create the mix and was even such a high usage as to not allow HEAT (Avid’s Neve channel emulation) to be added to the mix in the mastering stage. Reel Tape Saturation and Waves V Comp we’re used to add additional analogue realism and light control of the mix and to take strain off the Waves L3LL Ultramaximiser to bring the levels up to a steady K12 mastering volume. Air stereo width was added while monitoring the Phasescope to allow for a full stereo field. Blue Cat FreqAnalyst was used for frequency analysis, Waves C4 Multiband for multiband compression and Blue Cat Peak Meter to allow the mix to be monitored to a K12 volume (-12dBfs RMS average).

To conclude the project was a great success and was even filmed whilst being produced! Please see below for some audio snippets. The plan is to utilise the recording/video in BOA marketing!

Vocal Recording

Check out Stuart Eaves’s post on the recent vocal recording sessions I’ve been involved with. Some great vocals being recorded for Lauren Wright with her vocal coach Carrie Garrett from Rockstar Vox.

Univibe studios – Drum recording – Bass recording

Thought I’d upload a few pictures of what I did for my birthday this year.

Recording session at Univibe studios for drums for Lauren Wright’s upcoming album. What a lovely studio right next to PMT music on Birmingham’s Eastside, a real gem with a vintage DDA AMR24 inline mixing desk routed into Pro Tools HD.

My particular favourite mic was the sub kick mic for the extra LF in the kick drum (I think it was similar to a Yamaha SKRM100).

Back recording bass and guitars at home in logic with plans to mix large amounts in Pro Tools 10 when it arrives. I’m recording my bass parts DI into Logic and use amplitube amplifier modelling to get an effective sound. Lots of comping here, have a look at the screenshots in the slideshow and a listen to the rough drums and bass sample below.

Lauren Wright album coming soon, stay tuned for more info!

Supporting Britney Spears – LG Arena Birmingham

What an exciting day. A career highlight in supporting Britney Spears as bassist for Lauren Wright at the LG Arena Birmingham.

Thank you to al the people who came to hear use play and asked for pictures, autographs and took away our laminated business cards advertising her new single. We we’re lucky enough to receive VIP gallery treatment as well as a close up preview of Britney’s touring gear.

Lauren’s first Single release coincided with the gig with the single “Kiss Me” with B Side “Spark” (Music and lyrics myself and Stuart Eaves) now available from itunes. It’s been an upmost pleasure composing and recording with Lauren and the band. May there be many more singles!

Check out some of the pictures and videos from the gig!
