MakeStimuli.LoadSoundfile(varargin)#

usage: tone=LoadSoundfile(params, samplerate) inputs:

param (should have the following fields:)
frequency - frequency of the tone (Hz) amplitude - sound pressure level of the tone (dB) duration - duration of the tone (ms) ramp - length of an rising/falling edge (ascending/descending ramp) (ms)

samplerate - sampling rate in hz

MakeStimuli.Make2Tone(varargin)#: Note: now we use absolute SPL instead of attenuation!!!

MakeStimuli.MakeAMNoise(varargin)#

MakeStimuli.MakeAMTone(varargin)#

MakeStimuli.MakeAOPulse(varargin)#: this is modified from MakePulse (which is meant for delivering voltage/current pulses and therefore corrects for axopatch scale factor)

this function just delivers a straight AO voltage pulse

MakeStimuli.MakeAOPulseTrain(varargin)#

MakeStimuli.MakeASR(varargin)#: makes an ASR (acoustic startle response) stimulus with a white noise prepulse and white noise startle pulse modified from makeASR

Note: now we use absolute SPL instead of attenuation!!!

MakeStimuli.MakeAsymGPIAS(varargin)#: Note: now we use absolute SPL instead of attenuation!!!

MakeStimuli.MakeBinTone(varargin)#: Note: this was the original header function tone=MakeTone(frequency,attenuation,duration,samplerate,ramp)

MakeStimuli.MakeBinWhiteNoise(varargin)#

MakeStimuli.MakeCFTrainTC(varargin)#

Creates a CFTrainTC type tone train (a tone train at CF followed by a

test tone) Input

cf - the freq of the tones in train ntones - number of tones isi - inter-stimulus interval, i.e. interval between the

start of previous tone and start of the next tone

toneduration - duration of an individual tone (ms)

frequency - frequency of the tone (Hz)
amplitude - tone amplitude (dB) start - start of the first tone after the trigger (ms) duration - total duration of the tone train (ms) %%???not used? mw 04.13.06 next - inter-tone-train-interval, i.e. when the next

tone train should follow the previous one (ms)

ramp - rising/falling edge of individual tones samplerate - sampling rate (Hz)

Output: pulse - the required waveform

MakeStimuli.MakeGapInNoise(varargin)#: Creates a gap stimulus consisting of a continuous background noise with a gap. The background noise is generated by MakeNoise, see that function for params to use.

given frequency, attenuation, duration, at a given sample rate, with an ascending/descending ramp of a given length, at a given SOA (stimulus onset asynchrony) All lengths (duration, ramp) are in ms frequency is in Hz, attenuation in dB Input:

frequency - frequency of the tone (Hz)

% % % % % % % % % % % attenuation - attenuation of the tone (dB) % % % % % % % % % % % !!!!!attenuation is relative to the max. sound pressure level % % % % % % % % % % % as specified in Prefs.m (pref.maxSPL)

amplitude - sound pressure level of the tone (dB) duration - duration of the tone (ms) samplerate - required sampling rate ramp - length of an rising/falling edge (ascending/descending ramp) (ms) probefreq - frequency of the probe tone (Hz) probeamp - sound pressure level of the probe tone (dB) SOA - stimulus onset asynchrony (time in ms between onset of tone and probe tone)

Output: tone - the specified tone (empty if unsuccessful)
