Abstract
A method performed by an audio source device that is communicatively coupled with an audio output device, the method includes obtaining an audio signal; receiving a volume adjustment; applying the volume adjustment to the audio signal; applying dynamic range compression on the volume adjusted audio signal; and applying an inverse volume adjustment to the compressed audio signal, where the inverse volume adjusted audio signal is to be transmitted to the audio output device.
Claims20
A method performed by an audio output device, the method comprising:
- driving a speaker driver of the audio output device to output an audio signal;
- obtaining, from a volume control of the audio output device, a user volume adjustment;
- generating, responsive to the user volume adjustment, an audio feedback signal;
- driving the speaker driver to output the audio feedback signal;
- transmitting, via a wireless connection with an audio source device, the user volume adjustment to the audio source device;
- in response to transmitting the user volume adjustment, receiving, via the wireless connection and from the audio source device, a processed audio signal based on the user volume adjustment;
- adjusting the processed audio signal based on the user volume adjustment;
- and
- driving the speaker driver to output the adjusted processed audio signal.
A wireless headset comprising:
- a speaker driver;
- a hardware volume control;
- a processor;
- and
- memory having instructions stored therein which when executed by the processor causes the wireless headset to:
- drive the speaker driver to output an audio signal;
- obtain, from the hardware volume control, a user volume adjustment;
- generate, responsive to the user volume adjustment, an audio feedback signal;
- drive the speaker driver to output the audio feedback signal;
- wirelessly transmit the user volume adjustment to an audio source device;
- in response to wirelessly transmitting the user volume adjustment, wirelessly receive, from the audio source device, a processed audio signal based on the user volume adjustment;
- adjust the processed audio signal based on the user volume adjustment;
- and
- drive the speaker driver to output the adjusted processed audio signal.
A processor of an audio output device that is configured to:
- drive a speaker driver of the audio output device to output an audio signal;
- obtain, from a volume control of the audio output device, a user volume adjustment;
- generate, responsive to the user volume adjustment, an audio feedback signal;
- drive the speaker driver to output the audio feedback signal;
- wirelessly transmit the user volume adjustment to an audio source device;
- in response to transmitting the user volume adjustment, wirelessly receive, from the audio source device, a processed audio signal based on the user volume adjustment;
- adjust the processed audio signal based on the user volume adjustment;
- and
- drive the speaker driver to output the adjusted processed audio signal.
