Ntụle CREPE Pitch
CREPE bụ ihe nlere mmụta miri emi nke na-eme atụmatụ ugboro ugboro (pitch) nke mgbama ọdịyo monophonic ozugbo site na ụdị ebili mmiri ya.
Nchịkọta
It set a new accuracy standard for pitch tracking, especially on noisy or difficult recordings.
Ime miri emi
CREPE (Convolutional Representation for Pitch Estimation), introduced in 2018 by Kim, Salamon, Li, and Bello, predicts the pitch of single-note (monophonic) audio such as a sung voice or solo instrument. Unlike classic algorithms like YIN or pYIN that rely on autocorrelation of the signal, CREPE is a deep convolutional neural network trained directly on time-domain audio frames. It frames pitch estimation as a classification problem: it outputs a probability distribution over 360 pitch bins spanning roughly six octaves, each 20 cents apart. Ọkọlọtọ nke nwere mgbakwasa kachasị elu, nke a nụchara anụcha na nkezi nha dị n'ime mpaghara, na-enye ọnụọgụgụ echere gbakwunyere akara ntụkwasị obi. CREPE proved markedly more robust than signal-processing methods, particularly under noise, and is now a standard component in many music and speech analysis pipelines.
Nghọta nka nka
CREPE takes a 1024-sample audio frame and passes it through six stacked convolutional layers, ending in a 360-unit output layer with sigmoid activations. Nkeji ọ bụla dabara n'otu nrụnye pitch nke nwere cents 20 iche n'ofe ihe dị ka octave isii. A zụrụ netwọk ahụ site na ọnụọgụ abụọ cross-entropy megide ebumnuche Gaussian gbadoro anya gbadoro ụkwụ na ezi pitch. At inference, the predicted frequency is the local weighted average of activations around the peak bin, and the peak height serves as a confidence value.
