Beat and downbeat estimation and playback

A system for facilitating beat estimation and playback, 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:
• receive beat metadata for an audio signal, wherein the beat metadata is generated based on beat timestamp data indicating timestamps of beats and/or downbeats for the audio signal, wherein the beat timestamp data is generated by utilizing the audio signal as input to one or more beat estimation modules that are configured to account for variations in tempo when determining the beat timestamp data;
• receive user input directed to causing playback of the audio signal;
• receive additional user input directed to configuring the system to cause presentation of beat and/or downbeat cues during playback of the audio signal;
• cause playback of the audio signal;
• and
• use the beat metadata to cause presentation of the beat and/or downbeat cues during the playback of the audio signal, wherein the beat and/or downbeat cues are caused to be presented in accordance with the timestamps of the beats and/or downbeats for the audio signal represented in the beat metadata.

A system for facilitating beat estimation and playback, 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:
• access an audio signal;
• separate the audio signal into a plurality of audio stems;
• utilize an audio stem of the plurality of audio stems as input to one or more beat estimation modules to determine beat timestamp data indicating timestamps of beats and/or downbeats for the audio stem, wherein the one or more beat estimation modules are configured to account for variations in tempo when determining the beat timestamp data;
• generate beat metadata for the audio stem based on the beat timestamp data;
• receive user input directed to causing playback of the audio stem;
• receive additional user input directed to configuring the system to cause presentation of beat and/or downbeat cues during playback of the audio stem;
• cause playback of the audio stem;
• and
• use the beat metadata to cause presentation of the beat and/or downbeat cues during the playback of the audio stem, wherein the beat and/or downbeat cues are caused to be presented in accordance with the timestamps of the beats and/or downbeats for the audio stem represented in the beat metadata.
