Encountering issues converting live audio to Base64 for a Shazam-like API. Revised Kotlin sample below:

class AudioHandler {
    fun beginRecording(tempFile: File) {
        val recorder = android.media.MediaRecorder().apply {
            setAudioSource(android.media.MediaRecorder.AudioSource.MIC)
            setOutputFormat(android.media.MediaRecorder.OutputFormat.THREE_GPP)
            setAudioEncoder(android.media.MediaRecorder.AudioEncoder.AMR_NB)
            setOutputFile(tempFile.absolutePath)
            prepare()
            start()
        }
    }

    fun completeRecording(recorder: android.media.MediaRecorder, audioFile: File): String {
        recorder.stop()
        recorder.reset()
        return android.util.Base64.encodeToString(audioFile.readBytes(), android.util.Base64.NO_WRAP)
    }
}

In my experience working with MediaRecorder and live audio processing, I found that creating a robust solution involves careful management of file I/O and ensuring that the recorder shuts down cleanly after stopping. For instance, I had an issue where the audio file was not properly flushed before the conversion, which could lead to incomplete data being encoded. I solved it by adding a slight delay to guarantee the file was completely written to disk. Also, checking for proper permissions and handling any potential race conditions between recording completion and file reading can prove essential.

hey, try making sure the file is completely closed before you read it. i had odd issues when the file wasn’t fully synched. also double check your buffering and permissions, they might be causing race condition issues.
