Method and Device for Audio Input Routing

Abstract

A method on a mobile device for processing an audio input is described. A trigger for the audio input is received. At least one parameter is determined for an audio processor based on at least one input characteristic for the audio input. The audio input is routed to the audio processor with the at least one parameter.

We claim: 
     
         1 . A method in a mobile device for processing an audio input, the method comprising:
 receiving a trigger for the audio input;   determining at least one parameter for an audio processor based on at least one input characteristic for the audio input;   routing the audio input to the audio processor with the at least one parameter.   
     
     
         2 . The method of  claim 1  wherein routing the audio input comprises:
 routing a first portion of the audio input from a buffer associated with a source microphone; 
 routing a second portion of the audio input from the source microphone. 
 
     
     
         3 . The method of  claim 2  further comprising:
 initializing the audio processor with the at least one parameter; 
 buffering the audio input in the buffer while the audio processor initializes; 
 wherein routing the second portion of the audio input comprises routing the second portion of the audio input from the source microphone when the audio processor has initialized. 
 
     
     
         4 . The method of  claim 3  wherein initializing the audio processor comprises sending a wakeup signal to the audio processor. 
     
     
         5 . The method of  claim 1  wherein determining the at least one parameter comprises:
 performing a lookup for the at least one input characteristic with an identifier associated with the audio input. 
 
     
     
         6 . The method of  claim 1  wherein determining the at least one parameter comprises:
 dynamically determining the at least one input characteristic based on the trigger. 
 
     
     
         7 . The method of  claim 1  wherein the at least one input characteristic comprises at least one of a sampling rate, quality indicator, frequency range, codec type, background noise level, compression feature, noise separation feature, or noise canceling feature for the audio input or a transmission latency associated with the audio input. 
     
     
         8 . The method of  claim 1  wherein routing the audio input comprises receiving the audio input from a remote microphone via a wireless transceiver;
 wherein determining the at least one parameter comprises determining the at least one parameter based on the wireless transceiver. 
 
     
     
         9 . The method of  claim 1  wherein routing the audio input comprises obtaining the audio input as a pre-recorded audio file. 
     
     
         10 . The method of  claim 1  wherein determining the at least one parameter comprises selecting an audio codec for the audio processor. 
     
     
         11 . A method in a mobile device for processing an audio input, the method comprising:
 receiving a trigger for the audio input;   selecting a microphone from a set of microphones based on the trigger, wherein the set of microphones comprises a local microphone of the mobile device and a remote microphone;   determining at least one parameter for an audio processor based on the selected microphone;   receiving the audio input from the selected microphone;   providing the audio input to the audio processor with the at least one parameter.   
     
     
         12 . The method of  claim 11  wherein the remote microphone is a Bluetooth-enabled microphone;
 wherein receiving the audio input comprises receiving the audio input over a Bluetooth connection to the Bluetooth-enabled microphone. 
 
     
     
         13 . The method of  claim 13  wherein determining the at least one parameter comprises selecting a sampling rate associated with the Bluetooth-enabled microphone if the blue-tooth enabled microphone is selected. 
     
     
         14 . The method of  claim 12  wherein determining the at least one parameter comprises selecting a sampling rate associated with the local microphone if the local microphone is selected. 
     
     
         15 . The method of  claim 11  further comprising selecting the audio processor based on the selected microphone. 
     
     
         16 . A mobile device for processing an audio input, the mobile device comprising:
 a non-transitory memory;   a processor configured to retrieve instructions from the memory;   a local microphone;   a wireless transceiver; and   an audio processor;   wherein:   the mobile device is configured to receive a trigger for the audio input, wherein the trigger indicates whether the local microphone or the wireless transceiver is an input source for the audio input;   the mobile device is configured to determine at least one parameter for the audio processor based on at least one input characteristic of the input source;   the mobile device is configured to route the audio input from the input source, based on the trigger, to the audio processor with the at least one parameter.   
     
     
         17 . The mobile device of  claim 16  wherein the mobile device is configured to receive the audio input as an analog audio input from the local microphone. 
     
     
         18 . The mobile device of  claim 16  wherein the mobile device is configured to receive the audio input as an analog audio input through the wireless transceiver from a remote microphone. 
     
     
         19 . The mobile device of  claim 16  wherein the mobile device is configured to receive the audio input as a digital audio input through the wireless transceiver from a remote microphone. 
     
     
         20 . The mobile device of  claim 19  wherein the wireless transceiver is one of a Bluetooth transceiver, Wi-Fi transceiver, or cellular transceiver.
