- PlaySound( <URL> )
- Plays an MP3 (.mp3) file
- Examples:
PlaySound("http://static.geogebra.org/welcome_to_geogebra.mp3")PlaySound("#J2sQQfwQ")plays an .mp3 that has been uploaded to GeoGebraPlaySound("https://drive.google.com/uc?id=0B7xCmZaU3oU2eXFNUzd6ZlZJS0U&authuser=0&export=download")plays an .mp3 from Google DrivePlaySound("https://www.dropbox.com/s/27skpv82odjp7ej/material-1264825.mp3?dl=1")plays an .mp3 from DropBox
- Note: To work on iOS (and also if you want immediate playback) then you can encode the .mp3 as an inline base64-encoded data: URL, see https://www.geogebra.org/m/wztkqxuv for an example. It must start with the exact string
data:audio/mp3;base64,to work in GeoGebra Classic 5. You can use this utility to convert .MP3s into the syntax needed in GeoGebra https://test.geogebra.org/~mike/utils/base64Encode.html
- PlaySound( <Boolean Play> )
- Pause or resume play (not MP3 files)
PlaySound(true)= play,PlaySound(false)= pause.
- PlaySound( <Function>, <Min Value>, <Max Value> )
- Plays a sound generated by Function, a time-valued function with range [-1,1]. The time units are seconds and the sound is played from time Min Value to Max Value. Sound is generated by 8-bit samples taken at a rate of 8000 samples per second.
- Example:
PlaySound(sin(440 2Pi x), 0, 1) - This plays a pure sine wave tone at 440 Hz (musical note A) for one second.
- PlaySound( <Function>, <Min Value>, <Max Value>, <Sample Rate>, <Sample Depth> )
- Plays a sound generated by Function, a time-valued function with range [-1,1]. The time units are seconds and the sound is played from time Min Value to Max Value. The sampling method is specified by "Sample Depth" and "Sample Rate".
- "Sample Rate" is the number of sample function values taken each second. Allowable values are 8000, 11025, 16000, 22050, or 44100
- "Sample Depth" is the data size of a sample in bits. Allowable values are 8 and 16.
- PlaySound( <Note>, <Duration>, <Instrument> ) (GeoGebra Classic 5 only)
- Plays a MIDI note.
- Note is an integer from 0 to 127 that represents a musical note given by the table below. When note = 60 a Middle C is played.
- Duration is the time to play the note in seconds.
- Instrument is an integer that represents the synthesized instrument used to play the note. See technical specifications for possible instruments.
- Most instruments are supported, but there are differences between computer platforms.
