Latency enhanced note recognition method in gaming

A method for note recognition of an audio source in an application having a set of pitches to be played by a user, said method comprising the steps of;

• obtaining an audio input, having a plurality of sequential played pitches, from a microphone of a computing device,
• synchronizing the obtained audio input with the set of pitches to be played,
• determining when a current pitch in the audio input changes to a next pitch,
• outputting data indicative of the pitch to be played at the time a pitch is determined to have changed,
• determining the next pitch which was played, and
• updating the output data to the determined next pitch if the next pitch which was played is different from the output data indicative of the pitch to be played.

A non-transitory computer readable medium having stored thereon a set of computer readable instructions for causing a processor of a computing device to carry out a method for note recognition of an audio source in an application having a set of pitches to be played by a user, said method comprising the steps of:

• dividing an audio input into a plurality of frames, each frame having a pre-determined length,
• conducting a frequency analysis of at least a set of the plurality of frames,
• based on the frequency analysis, determining if a frame is a transient frame with a frequency change between the beginning and end of the frame,
• for each transient frame, outputting pitch data of a pitch to be played by a user at the time of the transient frame,
• conducting frequency analysis of at least one non-transient frame following the transient frame, based on the frequency analysis determining a pitch of the frame,
• checking if the determined pitch of said following frame is the same as the output pitch to be played and if not, outputting the determined pitch data for the following frame.
