gone

A simple application that just plays a pure tone

This application is based on the example of the oto library, which is used by this application.

Usage

Play a frequency:

gone [options] [frequencies] [duration]

The frequencies are played for the duration and if one frequency finishes, the next starts (the duration must be the last argument).

Options

Option	Usage
-samplerate	sample rate
-channel	number of channel
-bitdepth	bit depth in bytes

Build

Requires Go for compilation, gofumpt for code formatting and golangci-lint to run linters.

To build the code

make

or

make build

or if you don't have make installed

go build

To reformat the code:

make fmt

To run linters (will automatically format your code with gofumpt)

make lint

or if you don't want to format your code (linter may fail)

make lint-only

Use as library

You can use gone as a library to play frequencies. Therefore, install it with go get codeberg.org/qwerty287/gone.

Example

package main

import (
	"time"

	"codeberg.org/qwerty287/gone"
)

func main() {
	context, err := gone.NewContext() // returns a gone.Context with default values
	if err != nil {
		return
	}

	// if you need other values as sample rate, channel and bit depth use
	// gone.NewContextWithParameters(sample rate, channel, bit depth)

	frequency := 500.0
	// works best with times under 9 seconds
	duration := 6 * time.Second

	// PlayFrequency waits until sound is finished
	context.PlayFrequency(frequency, duration)

	// PlayFrequencyAndContinue continues after start playing the tone
	context.PlayFrequencyAndContinue(frequency, duration)

	// if you need the oto.Context directly
	context.OtoContext.Suspend()
}
