Hi everyone,
I am building a synthesizer with the Teensy 4.0 and the audio library. So far this has been delightfully accessible and I am liking the results. I ordered a MAX98357A Class D Amp to test the sound with an old bluetooth speaker which had defective bluetooth functions. For the higher frequencies this sound really nice, however I would like to have richer, fatter bass sounds. I would love to be able to replicate sounds like the Moog Bass!
Right now using a sine wave with at full amplitude and having the MAX98357A at full amplification you can barely hear frequencies below ~120Hz, the only audible sound is the speaker rattling on my desk.
Now I'm not really sure how to proceed.
I ordered some MCP6002 op amps just to tinker, and maybe amplify the lower parts for another speaker just for the bass parts, but since the lower frequencies need so much more drive I'm not even sure if the 5V amps will suffice, or if 12V are needed. I'd like to stay with 5V to power the system over USB.
One more thing: The MAX98357 does not have single ended output, though I'd like to use the Line-In from my guitar amp. I thought about using the MCP6002 to make a differential amplifier, which converts the signal to single ended for me to use. Is this a viable approach? Do you have any suggestions how I can improve my lower frequency sounds? Do I need more power, better parts?
Cheers
