A wireless microphone, or cordless microphone, is a microphone without a physical cable connecting it directly to the sound recording or amplifying equipment with which it is associated. Also known as a radio microphone, it has a small, battery-powered radio transmitter in the microphone body, which transmits the audio signal from the microphone by radio waves to a nearby receiver unit, which recovers the audio. The other audio equipment is connected to the receiver unit by cable. In one type the transmitter is contained within the handheld microphone body. In another type the transmitter is contained within a separate unit called a “bodypack”, usually clipped to the user’s belt or concealed under his clothes. The bodypack is connected by wire to a "lavalier microphone" or "lav" (a small microphone clipped to the user's lapel), a headset or earset microphone, or another wired microphone. Most bodypack designs also support a wired instrument connection (e.g., to a guitar). Wireless microphones are widely used in the entertainment industry, television broadcasting, and public speaking to allow public speakers, interviewers, performers, and entertainers to move about freely while using a microphone without requiring a cable attached to the microphone.

This disclosure provides methods, devices, and systems for streaming media from a Bluetooth-enabled peripheral device to a WLAN device over a wireless link (such as a P2P link). In some instances, a first peripheral device of a pair of peripheral devices selects values of a time-to-play (TTP) and a sequence number of a first audio stream, and synchronizes the selected TTP and sequence number with a TTP and a sequence number of a second audio stream. The first peripheral device rate-converts first audio data using a sample rate conversion ratio based on the selected TTP and sequence number, encapsulates the rate-converted first audio data into first RTP packets, and transmits the first RTP packets to the WLAN device concurrently with a transmission of second RTP packets from the second peripheral device to the WLAN device.
