Westerdal session April 2016

Session at Westerdal ACT, OSLO

Participants: Ylva Øyen Brandtsegg, Øyvind Brandtsegg

Objective: Studio use of cross_shimmer effect

Takes

Take 1: Cross_shimmer: Vocals as spectral input, Drumset as exciter

Take2: As above, another take on the same musical goal

Comments:

* Feedback not an issue in the studio setting, so the effect can be fully used as intended.

* The spectral input is taken from Øyvind’s vocal

* The musical effect works as highlighting and prolongation of features/pitches from the vocal input.

* The use of drum set as the exciter lends a more independent feel to the rhythmic action, but perhaps this evaluation is because it is not Øyvind who is playing the exciter signal (as compared with the Tape to Zero session)

*Subjective evaluation: This works quite well

* We would like to optimize the effect so that the analysis stage spends less CPU. It is  currently more CPU heavy than Hadron (1.5x)

Tape to zero 2016

Concert : Tape to zero festival, April 21 2016, Victoria Jazz, Nasjonal jazzscene Oslo

Participants: Maja S.K. Ratkje, Siv Øyunn Kjenbstad, Øyvind Brandtsegg

The objective, in the context of this research project, was live use of the “cross_shimmer” effect, testing musical applications and a recently developed feedback reduction mechanism.

Takes:
* Full concert, the cross adaptive effect is used in the first few minutes.

Comments:

* The effect is still not feedback safe, so the contact mic percussion pad was used as an exciter instead of taking the signal from the drumset as intended.

* The spectral input is taken from Maja’s vocal

* The musical effect works as highlighting and prolongation of features/pitches from the vocal input.

*Subjective evaluation: This works quite well

* We would like to optimize the effect so that the analysis stage spends less CPU. It is  currently more CPU heavy than Hadron (1.5x)

* We would like to have a more reliable feedback prevention system, enabling the use of the effect with an open mike exciter.
