Mayelana nalolu hlelo lokusebenza
Isebenzisa okokudlula komsindo ukukhiqiza imisindo bese ibona i-echo kumakrofoni. Isiginali echo singabonakala emephini, Kuguqulwe i-Fourier noma njenge-wave -form waveformform. Kuhle ukuphenya / ukukhombisa izimiso ze-acoustics.
I-RECORD_AUDIO Imvume yokusebenzisa imakrofoni ukuthola echo. WRITE_EXTERNAL_STORAGE Imvume yenzelwe ukuthi idatha igcinwe.
Izici / Imininingwane:
• Ukushintshashintsha imvamisa 44.1 kHz.
• Ukulinganisa isikhathi esingu-0.001 s kuya ku-5 s.
• Izindlela ezi-single / eziqhubekayo.
• Gcina idatha kumafayela we-CSV.
• Isizukulwane Sokuphamba:
• Ungashadile / Isitimela / iChirp.
• Isikwele / i-Sine waveforms.
• Ama-Envelopes e-Tukey / Hanning.
• I-Pulse frequency 20 Hz kuya ku-22.05 kHz.
• Isikhathi sokudonsa kufinyelela ku-1 s.
• I-MAP - Zibone ngeso lengqondo i-echo. Umbala noma umnyama nomhlophe. Inani le-Pixel kusuka ku-RMS noma inani eliphelele. Umugqa omusha womkhondo ngamunye we-echo. Hambisa idivaysi ngenkathi ushaya ngamandla ukukhiqiza imephu.
• I-Fast Fourier Transform (FFT) yamaphoyinti wedatha angama-8192 ukunquma okuqukethwe imvamisa phakathi kwemigqa ye-echo ukubona.
• Ukutholwa kwemvamisa ephakeme
• Ukulinganiselwa kwe-FFT
Okokukhonjiswa Kuphela. Sebenzisa Ukuvikelwa Kwendlebe uma kudingeka. Ngenxa yemikhawulo ye-dB yemakrofoni ejwayelekile ye-dB kumadivayisi amaningi, isibonakaliso se-echo esikude kungenzeka sibuthakathaka kakhulu ukuthola kahle ngaphandle kokuthi ukukhuliswa okwengeziwe noma i-echo eqinile ikhona.
Okokuzijabulisa / kokufundisa / kocwaningo. Lokhu akuyona i-Ultra futhi AKUFANELE noma yimuphi umcabango wezokwelapha. Lolu hlelo lokusebenza lungadala umsindo omkhulu ocasulayo, ngakho-ke sebenzisa ukuvikelwa kwendlebe uma kudingeka.

Ukuphepha kuqala ngokuqonda ukuthi onjiniyela baqoqa futhi babelane kanjani ngedatha yakho. Ubumfihlo bedatha nezinqubo zokuphepha zingahluka kuye ngokusebenzisa kwakho, isifunda, nobudala. Unjiniyela unikeze lolu lwazi futhi angalubuyekeza ngokuhamba kwesikhathi.
