Human interface board

dr hydra

I got a new project that I would like to use .wav file audio...I am very interested in using Kwabena Agyeman's KISSwav objects...first, will the KISS wav objects work directly with the human interface board for both the SD engine and audio output? For the output of the sound the human interface board describes a TRS cable...will the output from the TRS cable work through computer speakers?

They would have to be powered computer speakers as the HIB does not have an amplifier

(10) Audio and Composite Video Output
The A/V connector works with both 1/8” audio devices, such as headphones and speakers, and with
baseband video devices, such as TVs. The left channel draws its signal from Propeller I/O pin P11, the
right channel from P10, and the video from P12 through P15, with P12 as the most significant bit, P14 as
the least significant bit, and P15 as the aural subcarrier. The TRRS connector is compatible with TRS
cables, with the tip carrying left-channel audio, the ring carrying right-channel audio, and the sleeve
acting as the return path. When used with a TRRS cable, the tip carries left-channel audio, the outer ring
carries right-channel audio, the inner ring carries video, and the sleeve acts as the return path. The
signals are all line level signals with a 75 ohm impedance. The amplifier includes a 6th order low-pass
filter with an 8 MHz cutoff to significantly reduce the switching noise from the Propeller's duty mode
outputs.
