Frying
DESCRIPTION:
Friture is a real-time audio analyzer. The purpose of Friture is to help analyze an audio signal to understand the characteristics of this signal (fundamental, harmonics, feedback, etc.), to describe the source/room/receiver behaviour (reverberation, gain peaks, etc.), or to make adjustments in the preprocessing (room equalization). This is achieved by providing a set of widgets to visualize audio data:
- 2D Spectrogram Widget: Iyo 2D spectrogram widget inoratidza odhiyo data inopesana neiri frequency uye nguva, mune inotenderera-yakatarisana-nguva fashoni. Iyo nguva-frequency resolution yechiratidziro inogadziriswa nehurefu hwehwindo reFourier shanduko (seyenguva shoma yekupindura yewijeti yespectrum). Izvo zvakare zvinoganhurirwa nekugadziriswa kwechiratidziro chako mumapikiseli.
- Spectrum widget: Iyo spectrum widget inoratidza odhiyo data inopesana ne frequency. Izvi zvakanyatsokodzera kuona maitiro eiyo tha chiratidzo: yakakosha frequency, harmonics, mhinduro frequencies, etc. Nguva yekupindura yechiratidziro inogadziriswa. Nguva shoma yekupindura yakabatana nehurefu hwehwindo reFourier shanduko. Kune FFT yemapoinzi zana nemakumi maviri nemana, uye nekupihwa mwero wesampling we48000 Hz inoshandiswa naFriture, nguva shoma yekupindura ndeye 1024/48000 = 21.3 ms. Pamusoro pezvo, iyo widget inokwevera mapeaks kune yega frequency chikamu. Aya nhongonya anoisa maxima achangoburwa eiyo spectrum, uye anotanga kudzikira nguva pfupi mushure mekusvikwa kwepamusoro. Pakupedzisira, chikwangwani chinoratidza kuwanda kwehuwandu hwepasi rose hwehuwandu.
- Octave Spectrum widget: Iyo octave spectrum widget inoratidza odhiyo data rinopesana nenguva, zvakafanana neSpectrum widget. Dhata redhiyo rakaiswa mumabhini efrequency ane chidimbu-che-octave upamhi. Imwe neimwe frequency bin mhedzisiro yechidimbu-che-octave sefa.
- Scope widget: Iyo scope widget inoratidza odhiyo data maringe nenguva. Chiyero chenguva chinogadziriswa. Iyo inoratidzira inowiriraniswa maererano neinotungamira-kumucheto kwechiratidzo chakamisikidzwa pakati peiyo nguva axis, sezvingaitwa zvechinyakare.
- Level widget: Iyo nhanho widget inoratidza simba repamusoro (25 ms mhinduro nguva, i.e. pakarepo) uye RMS simba (300 ms mhinduro nguva) mudBFS (dB Yakazara Scale). Kana iyo 2-channel modhi ikagoneswa, inoratidza mazinga ega ega chiteshi pachiyero chakasiyana.
