CREPE Pitch Estimation
CREPE yakadzika-yekudzidza modhi inofungidzira iyo yakakosha frequency (pitch) ye monophonic odhiyo siginecha yakananga kubva kune yayo mbishi waveform.
Pfupiso
It set a new accuracy standard for pitch tracking, especially on noisy or difficult recordings.
Kudzika Kwakadzika
CREPE (Convolutional Representation yePitch Estimation), yakaunzwa muna 2018 naKim, Salamon, Li, naBello, inofanotaura kukwirira kwenoti imwe chete (monophonic) odhiyo senzwi rakaimbwa kana chiridzwa choga. Kusiyana neyakajairwa algorithms senge YIN kana pYIN inotsamira pane autocorrelation yechiratidzo, CREPE yakadzika convolutional neural network yakadzidziswa yakanangana nenguva-domain odhiyo mafuremu. Iyo inomisa fungidziro yepitch sedambudziko remhando: inoburitsa mukana wekugovera pamusoro pe360 pitch bins inotenderera ingangoita matanhatu octaves, imwe neimwe masenti makumi maviri. Ibhini rine yakanyanya activation, yakakwenenzverwa neavhareji yakayerwa yemunharaunda, inopa iyo inofungirwa frequency pamwe nechiratidzo chekuvimba. CREPE yakaratidza kusimba zvakanyanya kupfuura nzira dzekugadzirisa-chiratidzo, kunyanya pasi peruzha, uye iko zvino chave chinhu chakajairwa mumimhanzi mizhinji uye mapaipi ekuongorora kutaura.
Technical Insight
CREPE inotora 1024-sample odhiyo furemu uye inoipfuudza kuburikidza matanhatu akaturikidzana convolutional layer, ichipera mu360-unit yekubuda layer ine sigmoid activation. Chikwata chega chega chinofanana nebhini rekupinza rakaparadzana nemasendi makumi maviri pamativi anosvika matanhatu octaves. Iyo network inodzidziswa nebhinari muchinjiko-entropy kutarisana neGaussian-blurred chinangwa chakatarisana nepitch yechokwadi. Pakunongedza, iyo yakafanotaurwa frequency ndiyo yenzvimbo yakayerwa avhareji yeavhareji yeavhareji yakatenderedza bhini repamusoro, uye hurefu hwepamusoro hunoshanda sehukoshi hwekuvimba.
Strategic Impact
Svika uye svika
Inonatsiridza kusvikika kuburikidza nekunyora, kurondedzera, uye mazwi ekubatanidza.
Mutengo uye bhajeti
Zvikwata zveMedia zvinogona kutumira odhiyo yakakwenenzverwa nekukurumidza nemabhajeti madiki.
Kumhanya uye chiyero
Masisitimu anotarisana nevatengi anogona kugadzirisa kutaurirana kwekutaura pamwero mukuru.
Ramangwana reCREPE Pitch Estimation
Pitch estimation iri kufamba yakanangana nemamodhi akabatana anobata polyphony (manotsi akawanda panguva imwe chete), yakaderera latency ye-chaiyo-nguva tuning uye auto-kuwirirana, uye madiki madiki akadhindwa anomhanya panhare nemidziyo yakadzamidzirwa. Zvivimbo zveCREPE zvinobuda zviri kuwedzera kupihwa mumabasa epasi senge otomatiki kunyora, kururamisa izwi, uye kujekesa kuita ongororo. Kuzvitarisira wega uye maitiro akawanda anodzidza kukwirira padivi petimbre uye kutaura zvinogona kuwedzera CREPE-maitiro echokwadi kupfuura yakachena monophonic odhiyo.
Real-World Implementation
Kuteedzera kurira kwemuimbi kune chaiyo-nguva tuning mhinduro mumapurogiramu ekudzidzira mazwi
Kutyaira otomatiki-tune uye pitch-kururamisa maturusi ane echokwadi yakakosha-frequency curves
Kunyora nziyo dzezviridzwa zvega muMIDI kana mashizha emumhanzi
Kuongorora inzwi uye vibrato mumimhanzi dzidzo uye tsvagiridzo yekuita
Njodzi & Guardrails
Kushandisa izwi zvisizvo uye njodzi dzekuedzesera dzinowedzera kana chibvumirano chisipo.
Kururama kunogona kudonha mumitauro, mataurirwo, kana nharaunda dzine ruzha.
Synthetic audio inogona kukanganisa kutaura kwechokwadi isina mavara akajeka.
Implementation Roadmap
Wana mvumo yakajeka yekutora inzwi, kugadzira, uye kushandisa zvakare.
Yedza mhando pavatauri vakasiyana uye mamiriro ekumashure.
Tsanangura apo munhu anofanira kuongorora kana kubvumidza zvabuda.
Label synthetic odhiyo uye chengetedza marekodhi ekuzvidavirira.

What is CREPE Pitch Estimation?
CREPE yakadzika-yekudzidza modhi inofungidzira iyo yakakosha frequency (pitch) ye monophonic odhiyo siginecha yakananga kubva kune yayo mbishi waveform. Yakaisa chiyero chitsva chechokwadi chekuteedzera kwepitch, kunyanya pane zvine ruzha kana zvakaoma kurekodha.
Chii chinonzi CREPE inofungidzira kubva pachiratidzo chekuteerera?
CREPE inofanotaura iyo yakakosha frequency, i.e. inonzwisisika nzwi, yemonophonic audio.
CREPE yakagadzirirwa kunyanya rudzii rweodhiyo?
CREPE inofungidzira kukwirira kwemasaini emonophonic akadai sezwi rimwechete kana chiridzwa choga.
CREPE inoronga sei iyo pitch-yekufungidzira basa mukati?
CREPE inoburitsa mukana wekugovera pamusoro pe360 pitch bin, ichibata fungidziro sechikamu.
Chii chinotora CREPE sekupinza kwayo kwakananga?
Kusiyana ne spectrogram-yakavakirwa nzira, CREPE inoshanda pane yakaomeswa waveform mafuremu kuburikidza neconvolutional layer.
Anenge ari kure zvakadii akaparadzana mabhini eCREPE?
CREPE inoshandisa 360 mabhini akaparadzana nemasendi makumi maviri, ichipa sub-semitone resolution pamaoctave matanhatu.
