Tuning estimation and modification

A system for facilitating tuning estimation and modification, comprising:

• one or more processors;
• and
• one or more computer-readable recording media that store instructions that are executable by the one or more processors to configure the system to:
• process an audio signal using one or more executable modules to generate estimated tuning pitch output indicating an estimated tuning pitch associated with the audio signal;
• after generating the estimated tuning pitch output, determine a modification to a playback tuning pitch based on (i) the estimated tuning pitch determined via the one or more executable modules and (ii) a target playback tuning pitch, wherein the target playback tuning pitch comprises a pre-set user-selected tuning pitch value or is determined by processing an audio recording of a musical instrument;
• after determining the modification to the playback tuning pitch, process the modification to the playback tuning pitch of the audio signal such that, after processing of the modification to the playback tuning pitch, the system becomes configured to play back the audio signal using a modified playback tuning pitch rather than the estimated tuning pitch obtained via the one or more executable modules;
• and
• after processing the modification to the playback tuning pitch, play back the audio signal using the modified playback tuning pitch rather than the estimated tuning pitch.

A system for facilitating tuning estimation and modification, comprising:

• one or more processors;
• and
• one or more computer-readable recording media that store instructions that are executable by the one or more processors to configure the system to:
• perform stem separation on an audio signal to separate the audio signal into a plurality of audio stems;
• for at least a particular audio stem of the plurality of audio stems, process the particular audio stem using one or more executable modules to generate estimated tuning pitch output indicating an estimated tuning pitch associated with the particular audio stem;
• present the estimated tuning pitch on a user interface;
• receive user input directed to the user interface, wherein the user input indicates a modification to a playback tuning pitch associated with the particular audio stem;
• process the modification to the playback tuning pitch to modify the playback tuning pitch associated with the particular audio stem such that, after processing the modification to the playback tuning pitch, the system becomes configured to play back the particular audio stem using the modified playback tuning pitch rather than the estimated tuning pitch obtained via processing of the particular audio stem using the one or more executable modules;
• and
• after processing the modification to the playback tuning pitch, play back the particular audio stem using the modified playback tuning pitch rather than the estimated tuning pitch.
