Lightweight library facilitates audio recording by abstracting platform-specific details, enabling unified management and configuration of audio recording, enhancing code reuse and consistency across applications.
KMP-Record is a lightweight Kotlin Multiplatform library designed to facilitate audio recording functionality across iOS and Android platforms. By abstracting platform-specific details, KMP-Record enables developers to manage audio recording in a unified manner, enhancing code reuse and maintaining consistency across platforms.
This library is in super-early stages so the API can change a lot. Using it at your own risk.
The library is available via Maven Central:
commonMain.dependencies {
implementation("dev.theolm.record:record-core:<latest_version>")
}
To start recording make sure the user provided the right dependencies and just call startRecording. This method will throw exception in case anything goes wrong.
Record.startRecording()
This should start recording the audio with the default configuration.
To stop the recording call the method stopRecording that will return the path of the saved audio.
Record.stopRecording().also { savedAudioPath: String ->
println("Recording stopped. File saved at $savedAudioPath")
}
You can also call the method Record.isRecording() to check the status of the Record.
To change the default configuration just call the method Record.setConfig and pass the configuration object.
Record.setConfig(
RecordConfig(
outputLocation = OutputLocation.Cache,
outputFormat = OutputFormat.MPEG_4,
audioEncoder = AudioEncoder.AAC,
sampleRate = 44100
)
)
For now the configuration options are pretty limited to MPEG_4 and WAV. If you need a different configuration (e.g. different format), please open an issue or a PR.
