Hi there!
I'm trying to build a FAUST-based guitar amp profiler (Kemper-like) on the teensy 4.0, currently using only external hardware and the standard audioshield (no custom input circuits). The signal path giving me the best results so far is:
Guitar - DI-BOX - Mixer with Preamp - Audioshield-LineIn
I use a balanced signal between the mixer and the shields line-in (substraction is done in FAUST), that reduces the noise to acceptable levels for everything up to AC/DC-like distortion, but it gets really bad from there on. The same FAUST-program, as well as the teensy using USB-audio input, runs super-silent, so I assume the audioshield is the noisy part.
Since I'm not into electronics so much, are there any standard prebuild boards, shields or ICs out there I could try? I only know of blackaddr's TGA Pro, but that doesn't ship to Germany.
Or is it an option to use an external ADC/DAC and using the SPDIF ins and outs? Would that affect the latency?
Looking forward to any replies
