I am trying to manipulate the output of an audio file. I have been using such things as high and low pass filters and I would love to use a simulation software such as PSpice to simulate before building.

I would need the audio input to be split into the right, left and mono channels to be used as input signals to my circuit.

Is there any software out there than can do such a thing?

  • \$\begingroup\$ you will want to get Audacity and learn. IF you can imagine what is needed to split the spectrum into bands or comb filter, It can do it. \$\endgroup\$ May 21 '17 at 3:23

If you wish to build the filters and such from components, many circuit simulators including the popular LTSpice can input and output WAV files. For example, in LTSpice and in Microcap.

However, if you do not want to define the filters with transforms or you simply want knobs to twiddle, use an audio program like Audacity (simple) or a full DAW like Reaper (free and very capable), which will let you use existing plugins or build your own plugins.

Yes, you can try Tina-TI. You have to use a wav file for this purpose. Take a general voltage source, go to its settings and there you have an option to input a wav file as the signal.

If you have an mp3, you should convert it to wav using Audacity.

  • \$\begingroup\$ With Audacity you have dozens of parametric filters and Spectrum Analyzer . A virtual recording studio for crossfading, stereo echo filtering and mono splitting. \$\endgroup\$ May 21 '17 at 3:30

  • \$\begingroup\$ LTspiceIV and Audacity are completely different. \$\endgroup\$ May 21 '17 at 3:44
  • \$\begingroup\$ Splitting tracks and conversion of formats could be done in Audacity. Even though you can apply direct filters from there, if you want to test the circuit-model of the filters and all, you have to use LTSpice or TINA. \$\endgroup\$ May 21 '17 at 6:21
  • \$\begingroup\$ @tonystewart ltspice does the same thing as Tina TI, not as Audacity \$\endgroup\$

I doubt LTSpice can perform the custom audio processing of Audacity to separate mono into pseudo-stereo.

enter image description here

Choosing a design can later be done in LTspice after you trying different audio spectral effects.
