- A small effect pedal based on the Teensy audio Library.
Processing an audio from the MeeBlip Anode 2.0.

pretty cool delay sound! sounds warm and analog,
although digital! and looks pretty cool, too!
Thanks :)
Sounds amazing. did you use only the teensy memory or some expansion chips?
Nice! I'm not sure how you built it, but it's totally neat.
Hi, great project! I'm doing something similar using a Teensy 3.1, the Audio Adaptor board and an Oled 0.96" display, just like you did. The thing is both the Audio adaptor and the OLed disp use SDA SCL signals of the Teensy board. How can you possibly handle the same signals for different purposes? I took a look to your blog and I couldn't find an answer to my problem. Thanks! Cheers, A.
P Antonio Hi! Those are lines from the I2C protocol. Multiple slave chips can exist on the same bus and each chip is communicated to with their own address. This address is set for example in the Adafruit OLED library with display.begin(SSD1306_SWITCHCAPVCC, 0x3C);
Tomash Ghzegovsky Oook,! Thanks, bye
Love this project, I've been trying to do pretty much the same thing, in an attempt to make a delay unit for an active speaker (delay tower). But I experienced a lot of noise-problems, possibly related to impedance or perhaps because I need to disable some auto-volume or set line-in-level and line-out-level for the chip differently. I use the line-in and line-out terminals on the audio board. Did you experience anything similar to this, and how did you fix it? Is there any chance, you can publish some of the source-code? (primarily for setting up the audio-part). I would be very grateful for any details, you can provide :-)
how complicated is it to give audio i/o to a Teensy for a hi-z instrument like a guitar? i guess there needs to be an opamp on the input side, some kind of voltage regulator to protect the teensy on both input and output, anything else? Is there a thread at PJRC you'd recommend by chance?
Take a look at this, haven't tried it myself but it seems suitable for guitar and price is right too: www.tindie.com/products/Blackaddr/arduino-teensy-guitar-audio-shield/
Do you think a Raspberry Pi Zero W would be a suitable alternative to use for this project or does it not have as much processing power/ real-time capability as a microcontroller like the Teensy?
I'm pretty sure you could use things like Pure Data to make even more complex effect chains. The down side is the overhead of loading a whole operating system.
