Note: The Audio & Video tab of the Recording Settings for Video dialog has the Webcam Settings section instead. You can click the up or down arrow in the spin box to change the duration as you want. To be more precise, before you click a button for a period of time, ActivePresenter will take a screenshot. This section is built exclusively for recording Software Simulation. You should select 256Kbps bit rate that can provide much better audio quality than 128Kbps bit rate does with a quite small file size. The higher the bit rate you select, the better the audio quality is. This is the number of bits that are conveyed per second. You can select one from four options from the Bit Rate list. Bit Rate: This option is only activated when you select the MP3 codec.Note: This option is only activated when you select the Vorbis codec. The higher the quality, the larger the output audio file size and vice versa. Quality: Select the audio quality in the range from 1 to 100.If there is no special audio quality needed, the mono channel is good enough for recording video demonstrations or software simulations. However, the stereo channel can provide listeners with a more natural experience. In comparison with mono, the stereo channel needs double storage size. Channels: Select Mono or Stereo from the Channels list.In ActivePresenter, it’s recommended that you should let this value be 4800 Hz. The higher the fidelity, the better the audio quality.Ī higher sample rate increases the fidelity and audio size and vice versa. Sample Rate: Sample rate decides the fidelity or the quality standard of the audio.Note: Using a lossy codec, the compressed audio will have lower quality than the original audio. Lossy codecs with less file size but not fully reserved quality ( Vorbis and MP3).Lossless codec having quality reserved ( 16-bit PCM).
