How to change audio sample rate?

[opticalix]

Audio recognition model I use requires 16khz sample rate. I try to add sink of remote audio:

AudioTrackSink {
            override fun onData(
                audioData: ByteBuffer?,
                bitsPerSample: Int,
                sampleRate: Int,
                numberOfChannels: Int,
                numberOfFrames: Int,
                absoluteCaptureTimestampMs: Long
            ) {}

and callback of local audio:

override fun onBuffer(
                    buffer: ByteBuffer,
                    audioFormat: Int,
                    channelCount: Int,
                    sampleRate: Int,
                    bytesRead: Int,
                    captureTimeNs: Long
                )

but 'sampleRate' I got is all 48khz. Is there any way to config the SAMPLE RATE?
