Audio Encoder Settings
The following table lists the Audio Encoder controls and settings:
Input Parameters
| Audio Encoder Setting | Default | Description/Values |
|---|---|---|
| Input | SDI1 (1-2) | Select the Audio Input for the encoder.
|
|
Basic Parameters
| Audio Encoder Setting | Default | Description/Values |
|---|---|---|
| Channel Mode | Stereo | Select the number and type of audio channels to encode:
|
| Bitrate | 128 kbps | Select the Audio Bitrate for the encoder:
Note As of v1.4, the Makito X4 allows lower audio encoding bitrates (intended for very limited bandwidth streaming situations), as well as higher quality audio encoding at higher bitrates. |
| Sample Rate (kHz) | 48 kHz | The number of audio samples per second taken from the incoming signal. 48 kHz only. |
| AAC-LC Algorithm | MPEG-2 ADTS | The audio compression algorithm:
|
| 0 dBFS Audio Level (dBu) | +6 dBu | (Analog Input only) Adjusts the maximum analog Audio Input signal level (0 dBfs) from 0 to +6dBU. Note This is useful in applications such as broadcast and streaming to allow higher audio headroom. |
| Language | n/a | (Optional) To specify the language of the input, start typing letters and select the language from the list. The language values are three-letter codes, defined in ISO 639-2 (https://www.loc.gov/standards/iso639-2/php/code_list.php). |
Statistics | n/a | Click Statistics to view statistics for the encoder. See Audio Encoder Statistics. |
Mute | n/a | Click Mute to encode silence instead of the selected audio input. For example, this may be used when you do not wish to encode the audio but the decoder being used does not support decoding of video only streams. |
Stop Start | n/a | Click Stop to stop an active encoder. Click Start to start or restart a stopped encoder. |
