Max MSP – Audio FX

• Delay
• Reverb (Dark Hall Reverb)
• Stutter

Progress Notes

Accomplished the following goals:

• My aim this week was to develop 3 Unique Audio FX to change real time with audio input in conjunction to the TD output data. 
• As shown below, I was successfully able to accomplish this by creating simple Audio FX (Delay, Reverb, Stutter).
• To control the feedback of Audio Output, I created a limiter on each gain slider by multiplying the audio output by 0.5 to decrease the volume before the audio output gets to the gain slide, to avoid possibility of feedback.

Trouble Shooting Software

• • Positives: Successfully developed 3 Unique Audio FX (Delay, Reverb, Stutter) by creating 3 separate value ranges using TD output data.
  • Issues: My concern is that currently I have to be very mindful of the volume levels as I have experienced feedback even with the set limiters. This can and will hinder the process as the interference is quite jarring and distracting.
  • Approach: Create a buffer section and smooth-out data output from TD to filter rate of changes for Audio FX (as also suggested by our Tutor, Philly, on March 11th Tutorial Session).

Upcoming Goals:

• Develop an Oscillator to change real time with audio input. To accomplish this, I located the following Youtube Tutorial:

” Max/MSP: Using Peakamp~ to Control Frequency of an Oscillator.”

• Develop a Gain Buffer to troubleshoot feedback issues. I located the following Max MSP Tutorial that analyzes the Audio Input and provides a very helpful tips regarding Audio Analyzation.

Tutorial Updates (March 11, 2025)

Feedback:

• Concerns regarding Unpredicatable Audio Feedback
• Suggestions to further develop the Max Patch by doing the following:
  • • • Create a Gain Buffer to eliminate possibility of feedback during installation.
      • Smooth out TD Data Output – to avoid static changes in Audio FX
      • Ensure that the Max MSP Patch serves as an accompaniment to the fixed composition created by Sound Director Ruolin, to ensure cohesiveness in audio presentation.
      • Consider including different types of Reverbs – via VST Plugins or by creating multiple.
        • • • • • Schroeder Reverb:
