Member Function Documentation

◆ generateChannels()

void openmsx::CassettePlayer::generateChannels	(	float **	buffers,
		unsigned	num
	)

overridevirtual

Abstract method to generate the actual sound data.

Parameters

buffers	An array of pointer to buffers. Each buffer must be big enough to hold 'num' samples.
num	The number of samples.

This method should fill each buffer with sound data that corresponds to one channel of the sound device. The same channel should each time be written to the same buffer (needed for record).

If a certain channel is muted it is allowed to set the buffer pointer to nullptr. This has exactly the same effect as filling the buffer completely with zeros, but it can be more efficient.

Implements openmsx::SoundDevice.

Definition at line 554 of file CassettePlayer.cc.

References PLAY.

◆ getAmplificationFactorImpl()

float openmsx::CassettePlayer::getAmplificationFactorImpl ( ) const

overridevirtual

Get amplification/attenuation factor for this device.

Normally the outputBuffer() method should scale the output to the range [-1.0..+1.0]. But sometimes it's more convenient to generate another output range. In later stages the output is anyway still multiplied by some factor. This method tells which factor should be used to scale the output to the correct range. The default implementation returns '1.0 / 32768.0'.
