I've been designing some filters using LTspice IV as part of a speaker rig, and i want to add their output to the modelling i am doing in matlab of the speaker response.
Does anyone know if LTspice IV can output as a data table or anything?
If not, is there any software which is free that can do this?
There is an export utility(Waveform Menu: File=>Export) that allows data to be exported to an ACSII file. There is also a 3rd party free utility written by Helmut Sennewald. It is available from the independent users' group LTspice : LTspice/SwitcherCAD III. This utility allows various forms of manipulation of the data including the ability to merge waveforms from different simulation runs.
