Editor

[Dirk Bruere at Neopax]

Further to the TMS project I'm looking for a cheap or free waveform editor.
I want to use a PC soundcard to play a suitable .wav file through an amp into
the coil.

The .wav is a series of pseudorandom pulses of millisecond duration at around
150Hz. I need an editor to create the file.

Any ideas?

Something like Matlab would be the choice here.

Since I don't own it and don't want to pay for the vast array of features I will
never use, does anyone have any other ideas? What I want seems simple - a
Windows GUI where I can draw a waveform and have the soundcard play it. It must
exist somewhere.

Any PC based audio signal generator s/w on the market that is free (or cheap)?

You can convert csv values easily to a sound file using sound editing
programs such as Cool Edit Pro. Just write a program in your favorite
language to spit out such a file and Robert's your uncle.

Would I want Robert to be my uncle ?

Take a look at Goldwave : Fully functional shareware with a bunch of
options.
which might or might not handle your need for a pulse sequence.

If I were doing this, I'd use Excel to generate the time points and then
fidget
the saved (text format) file into a .wav file after I'd understood the .wav
format. But I use Excel for lots of computations where others would use a
math package.

My favorite way to create .wav files is to use LTSpice. You use the
program to create a circuit that makes the waveform you want and then save the
voltage as a .wav file. You could use piece-wise signal sources to generate any
arbitrary waveform. Or if you have the math skills, you can use a signal source
that interprets a formula. If the generated waveform is random, you can run it
through all sorts of filters to bandlimit it.

You could even simulate a Moog synthesizer with it. I've used it to
generate ultrasound doppler bloodflow signals.

LTSpice is so nice that if it could cook, I'd marry it!

Cool Edit Pro - $299
Still looking...

Goldwave will probably do it but I have not tried. I got a copy of
that for free with a sound chip development kit.
