[sdiy] Generate WAV files with MacSpice?

[Ingo Debus]

Hello all,

LTSpice has a great feature: it can generate WAV files. This way you  
can listen to the output of your circuit before even building it.  
Further, you can generate a WAV file of an impulse response of a  
(fixed) filter, feed that into a convolution reverb which then will  
sound like the filter. This works, I have tried it.

Unfortunately, there's no Mac version of LTSpice. MacSpice cannot  
generate WAV files, but it can generate raw signal files. These files  
contain the signal in double (8 bytes) big endian format. Does  
anybody know a converter that would convert that into a more  
convenient audio file format (preferrably on Mac, on Win I could use  
LTSpice anyway)? Or is there any other way to get the output of  
MacSpice in a sound file format?

I tried Switch, but that program doesn't convert double (8 byte)  
float. It does convert 4 byte float though.
Switch is available here:
