When using the js-sdk to collect audio, you want to display the spectrum in real time, but you do not know how to detect the recording parameters in this case. Is there a good way to achieve the desired effect like webaudiodemos. appspot. comAudioR? When using the js-sdk to collect audio, you want to display the spectrum in real time, but you do not know how to detect the recording parameters in this case.

Shannon theorem: c = wlog2 (1 + S/N) or C = WLB (1 + S/N) (LB and log2 are the same)C Indicates the channel capacity, measured in bits per second (B/S)W indicates the bandwidth required for transmitting information. The unit is Hz;S represents the average signal power;N represents the average noise power;Spectrum Efficiency: transmission capability per unit frequency:C/W = LB (1 + S/N)There is a relationship between Shannon theorem and

Recently, IEEE Spectrum has unveiled one of the most popular programming language rankings. The leaderboard screened 12 indicators, combined with 10 sources (including IEEE Xplore, Google, GitHub), and finally ranked the following (out of 100, the higher the ranking, the more forward), of which the top ten programming languages were: 1. Java 2, C 3. C + + 4, CNo. 5. Python 6. JavaScript 7. PHP 8. Ruby 9. SQL 10, MATLAB Ranking by type, the leaderboard

Show (Need to first convert MP3 to SWF, and then processing the converted SwF to correctly display the sound spectrum), it can be said that Flash8 and the following version of The voice support is limited, and FLASH9 in this regard has been upgraded, the ability to deal with the sound greatly improved, Below is a small example of how the spectrum is actually displayed when playing music with FLASH9 (refer t

P68Spectrum: The vast majority of signals can decompose a number of different frequency sine waves, in some sine waves, the lowest frequency is called the fundamental wave of the signal, the rest is called signal harmonics, equivalent to the basic frequency of the signal. The sine wave component, which has a frequency equal to the base frequency integer, is called harmonics.Comparison of image and spectrum after logarithmic transformation of 1.fft2 Ff

When capturing audio with JS-SDK, you want to be able to display the spectrum in real time, but do not know how to test the recording parameters in this case. The effect you want to achieve is like Https://webaudiodemos.appspot.com/AudioR ... Is there a better way to implement it?

Tiantie has become a hot topic in academia, industry, and industry. IEEE spectrum published a feature article on the ladder on September 13, August. It can be seen that its idea has a wide influence. Spectrum's first edition features ArticleIt is generally very interesting to write. This article is no exception. We strongly recommend that you read it as soon as possible. Maybe, in our lifetime, we could have the opportunity to take the ladder to the
