Getting started with NVDA

Getting started with NVDA

NVDA is a free and open source screen reader from NVAccess. It is available for the Windows operating system and officially supports Internet Explorer, Firefox, and Chrome web browsers. There is also a ton of braille display support!

NVDA is available for download here:

After everything is installed you can press Ctrl + Alt + n to start NVDA. Quitting NVDA is done by pressing NVDA + q, then enter at the prompt.

The NVDA Modifier Key

Each screen reader has a special key or key combination to perform tasks. NVDA’s default keyboard modifier key is the insert key. So, for example, to start reading a web page, you could press insert + down arrow. As an option, if you are using a laptop you can also use the caps lock key as a modifier. This can be set in the Preferences > Keyboard settings... menu.

リアルタイムスペクトラム・アナライザーを作ってみた。 PortAudioのPython版PyAudioとnumpyに依存。 実行すると横並び64個の0〜9の数値の表示が流れ続けます。 マイク音声を入力すると周波数成分別に数字が大きくなります。 リアルタイム16Kサンプリングの512点FFTがCore-i5レベルCPU2%程度の使用量で動きます。 内部ではちゃんと周波数の値が計算されています(ループの中で計算する必要はなかった・・・) - 口笛で音階をつけると大きな数字が現れる場所がスライドします。 - 打撃音は全部の数値が増えます。
