You can use the code to control the volume by increasing or decreasing this number to increase or decrease the volume. Since the default volume was incredibly high, we included a tone_volume variable in the sine wave code. Even though the button switch involves digitalio, we're using an A-pin so that the same setup code will work across all the boards. # SPDX-FileCopyrightText: 2018 Kattni Rembor for Adafruit Industriesįirst we create the button object, assign it to pin A1, and set it as an input with a pull-up.

This doesn't need to match the length of the sound. Duration indicates the duration of the synth item, before the next item is presented.Length indicates the length of the sound (in milliseconds).Setting pan to -20 or 20 completely mutes the right or left channel, respectively. Pan turns the right (negative values) or left (positive values) channel down.Note that the decay occurs within the length of the sound. Decay is the time it takes for the sound to die out (i.e.Attack is the time it takes for the sound the reach maximum volume (i.e.Waveform can be set to sine, sawtooth, square, or white noise.'sound' to wait until the sampler has finished playing.In addition to a numeric value, you can set duration to: For example, if the duration of the sampler is set to 0 ms, OpenSesame will advance directly to the item that follows the sampler (e.g., a sketchpad), while the sound file continues playing in the background. This doesn't need to match the length of the sound file. Duration indicates the duration of the sampler item, before the next item is presented.For example, a value of 100 ms means that the sound file will start silent, and build up to maximum value in 100 ms. Fade in indicates the fade-in time for the sound file.A value of 0 ms means that the sound file will be played back completely. For example, a value of 100 ms means that playback will be stopped after 100 ms, regardless of how long the sound file is. Stop after indicates for how long the sound file should be played.Pitch indicates the playback speed, where 1 corresponds to the original speed.For full panning, enter 'left' or 'right', Volume between 0 (silent) and 1 (normal volume).Sound file indicates the file to be played.If your sample appears to be sped up (high pitch) or slowed down (low pitch), you can adjust the sampling rate of your sound file in a sound editor, or change the sampling rate used by the OpenSesame sampler backend (under 'Show backend settings and info' in the General tab). Sound files are always played back at the sampling rate that is used by the OpenSesame sampler backend. ogg files are supported if you want to use a sound file that has a different format, you can convert it using the free software Audacity. The sampler plays back a single sound file, typically from the file pool.
