The vertical amplifier circuit at the end of the script has been modified to suit Corona688's comment about using analogue modems' isolating 600 Ohm 1 : 1 transformers. C2 is AC coupled to the transformer now and the emitter resistor is now connectd to ground.
No other changes have been done. The original circuit can still be used without modification so there is no need to alter it.
There is now a SWEEP generator built in and is used for bandwidth and LF roll-off tests.
It goes from 4KHz down to about 85Hz and back, twice. It is a poor squarewave that has a certain amount of sinewave ringing on it, this a function of 8 bit depth and 8000Hz sampling speed but was easy to implement.
Its prime objective is to quickly see how the waveform differentiates at LF and integrates at HF/MF giving a quick assessment of the total amplifier BW...
The command is SWEEP<CR> to run it...
Only three modes can play it back inside the code:-
afplay for OSX 10.7.5 and above.
aplay for Linux machines using ALSA.
/dev/dsp for CygWin and Linux machnes with OSS and PulseAudio.
It does not autorun inside a separate xterm window but is there to create the files to be run on a separate machine.
The manual has been updated to include this and the file is now 134772 bytes in size... EEK!

My problem is, I can... (2 Replies)

Hi all...
Well I have not been inactive but working out how to make OSX 10.14.x command line audio player have a variable sample rate.
This is a back door as afplay does not have a sample rate flag unlike aplay for ALSA, in Linux flavours.
This is a DEMO only but a derivative of it will... (2 Replies)
