aubio

Load the audio file into aubio.

Use aubio's pitch tracking to estimate the fundamental frequency of each note.

Use onset detection to determine the start times of each note.

Quantize the detected pitches and durations to the nearest musical note values.

Generate a MIDI file or sheet music from the quantized notes.

Capture the audio stream from the DJ mixer.

Use aubio's beat tracking algorithm to estimate the tempo of the current track.

Adjust the playback speed of the next track to match the tempo of the current track.

Use phase locking techniques to synchronize the beats of the two tracks.

Transition seamlessly between the two tracks.

Load an audio file of a sound effect into aubio.

Use aubio's MFCC extraction to analyze the spectral characteristics of the sound.

Use onset detection to identify the attack and decay phases of the sound.

Modify the MFCCs or onset times to create variations of the sound effect.

Synthesize the modified sound effect using an audio synthesizer.

Capture the audio stream from a musical instrument.

Use aubio's pitch tracking to detect the notes being played.

Use onset detection to detect the timing of the notes.

Map the detected notes and timing to control parameters of a sound synthesizer or effects processor.

Generate music in real time based on the musician's input.

Load the audio file into aubio.

Analyze the audio for transient noises (clicks/pops) using onset detection.

Use spectral analysis (e.g., FFT) to identify and remove persistent noise.

Reconstruct the audio signal with the noise and artifacts removed.
