敘述:Frequency Generator 頻率發聲器
支援語言:英語
這是一個帶有一個振盪器的聲音或信號發生器。它可以播放可自定義的波形,因此您可以控制峰的數量,方向,幅度和銳度。
這種樂器清楚地展示了聲音的物理特性,最重要的是你可以看到人類聽不到頻率而是振幅加速度(或峰值銳度)。此外,聲波內的峰值位置或方向不會影響人類對聲音的感知。您甚至可以聽到峰值的0.2Hz聲音足夠尖銳,並且信號的頻率(自重複性)對我們的耳朵實際上沒有意義。在自然界中沒有完美的重複波浪,聲音具有更多的自由波性質,因此我們的聲音識別能力的重要性在於峰值銳度以及峰值的數量和幅度:)
音頻的頻域和FFT不能錯誤和誤導。
因此,在時間領域工作並處理這些高峰,以推動科學和音樂的發展!
該應用程序可用於物理,音樂或聲音,教育或任何東西。
振盪器範圍0.2Hz - 20KHz
具有多達10個峰值控制點的任意波形。
峰寬和可能的峰值振動
停止使用FFT進行聲音 - 這是CPU昂貴且出錯了:)
This is a sound or signal generator with one oscillator. It can play customisable wave form so you control the number, direction, amplitude and sharpness of the peaks.
This instrument clearly demonstrates the physics of the sound and most importantly you can see that humans do not hear frequencies but amplitude acceleration (or peak sharpness). Also the peak position or direction inside the sound wave has no impact of human perception for the sound. You can even hear 0.2Hz sound of the peak is sharp enough and the frequency (self repetitiveness) of the signal is not actually meaningful for our ears. In nature there are no perfectly repeated waves and the sound has more free wave nature so what is important fo our sound recognition abilities is the peaks sharpness and the number and amplitude of those peaks :)
Frequency domain and FFT for music can’t be more wrong and misleading.
So work in time domain and handle those peaks to move the science and music ahead!
The app can be used for physics, music or sound, education or what ever.
Oscillator range 0.2Hz - 20KHz
Arbitrary waveform with up to 10 peak control points.
Peak width and possible peak vibration
Stop using FFT for sound - it is CPU expensive and dead wrong :)
