Sound Analyzer Basic 是一款僅使用移動設備來分析音頻信號的應用程序。
其主要功能是實時顯示頻率（Hz）和幅度（dB）頻譜，但也可用於顯示頻譜隨時間的變化（瀑布視圖）並同時顯示波形（波形視圖）。
SoundAnalyzerBasic的頻率測量精度非常高，在相對低噪聲的環境下，測量誤差一般在0.1Hz以內。 （使用默認設置測量時）

主要功能
- 峰值頻率顯示功能（實時顯示突出頻譜成分的頻率[Hz]和幅度[dB]）
- 通過觸摸操作改變顯示範圍
- 可在對數和線性刻度之間切換頻率軸刻度
- 瀑布視圖（顯示光譜隨時間的變化）
- 波形視圖（顯示聲音波形）
- 截圖功能（帶定時器）

關於高頻範圍頻譜
該應用程序允許將最高頻率設置提高至 96 kHz，但高於 22.05 kHz 的設置適用於具有高質量音頻輸入的設備，不適用於通用設備。
在當今市場上的大多數設備中，高於約 22 kHz 的高頻範圍內的數據會被濾除。由於即使設置值較高，也無法獲取去除範圍內的數據，因此該範圍內的頻譜僅包含小於-60 dB的微弱噪聲是正常的。
但是，根據型號的不同，在 48 kHz 和 96 kHz 等特定頻率下可能會出現因濾波器處理而產生的較大噪聲。

Features
- Wide range of analysis parameter settings
- Frequency (horizontal axis) can be switched between logarithmic and linear scales
- Display range can be changed (zoom, scroll) by touch operation
- Automatic screen rotation (can be fixed by setting)
- Real-time display of peak frequencies and amplitudes (up to 10)

Analysis parameters
- Maximum frequency: Selectable from 2 kHz to 96 kHz (The frequency that can be set depends on the model you are using.

- Update rate: 45fps, 30fps, 15fps, 5fps, 1fps

Notes.
This app allows you to increase the maximum frequency up to 96kHz, but please note that the settings above 24kHz are mainly for high-performance microphones, not for built-in microphones of common devices.
(In general devices available on the market today, data in the high frequency range above about 22 kHz is pseudo-created by interpolation processing on the hardware. Normally, the spectrum in this range contains only a faint noise of less than -60 dB, but depending on the model, Larger noises may appear at certain frequencies such as 48 kHz or 96 kHz due to the interpolation process described above.
