UTS_Audio[編輯]
=== install file: UTS_Audio01000010.exe ===
- load audio dll
- assign device (output and capture)
- generate freq
- analysis
- log result
可分析
- 即時的 音源
- 也可以分析 .wav 的檔案 sample code 裡面都有
- 可由device name or GUID 來選擇要輸入/輸出的 裝置 GUID 空白時就以 default device 來控制
once install files will stay under c:\Program Files (x86)\Logitech\UTS\UTS_Audio\
- UTS_Audio.dll
- UTS_Audio_dlg.exe

調整訣竅:
- 發出的音量 (觀察 RMS value )要適當. 在合適的音壓之下. 才會有好的THD 表現
- 在沒有回音 的無響箱或無響室, 調整音量, 觀察THD 變化. 得到穩定且低的 THD 值. 就是 整個系統 ( 輸入源. 輸出檔) 的良好設定.
- 音量過大聲會失真(有二次諧波變大), 過小背景雜音比例大, THD 也會不好) 以 Lenovo 筆電 用耳麥 為例 音壓 (RMS value 應該落在 2000mV左右 THD 表現比較好
- 經過不斷的試驗才能找到 合理的音量 得到好的THD
聲源的 優化:
- 業界通常用 Hanning 作為音源的pre-process 提供給FFT分析軟件分析. 得到的spectrum 比較一致.
專有名詞
- THD ( Total harmonic distortion ) 总谐波失真- 维基百科，自由的百科全书
- Peak Power / Peak Frequency 在 Frequency domain 裡面最高位置的 頻率( x 軸) & level (Y 軸)
Frequency Response (頻率響應的測試)
- 給一段 頻率範圍 (例如: 1000Hz ~ 6000Hz )
- 設置想要達到的dB值 (例如 -40 dB)
- 設置喇叭(音源) 與 輸入(mic) 的相對位置.
- 將輸出reset 到輸出最大音量 (每次都要做(有bug必須要做))
- 執行 Frequency Response. ap 會開始調適適合的音量 來符合你的期望dB值 (調整不到則會 fail 跳出 )
- pass 的話 會輸出 每個頻率所需要的音量大小
用於分析 麥克風與 喇叭的頻率響應 敏度 範例圖如右
