Frequencies Analysis apps

nagramen

唔洗錢玩玩，I have downloaded the Spectrum Analysis apps and used it with Stereophile Test CD for fun testing. Below is the result:

Stereophile Test CD 話出負20dB 都可以tune 到差不多岩，preamp volume knob was set to 10 o'clock.

其實，我的房間是正方形，想試吓测唔測到有70Hz注波(standing waves)，但Analyser apps can't tell 喎!

I would consider the accuracy of the microphone, even sound level meter such as Radio Shack is known to need measurement adjustment.

The microphone is the one in my samsung Note3.

什么樂器出到5000Hz 以上呢?

wilmer兄， It seems that very few musical instruments can emit 5000+ Hz.

點會無？Harmonics都係樂器個處出來的。

主流樂器嚟講，唔計 harmonic，基本係冇，不過冇可能唔計 harmonic，冇左 harmonic 我地根本分辨唔出樂器種類，所以如果真係要做 analysis，就要睇吓你要 check d 乜。

Need to count harmonics too!
