If the recorded audio quality needs improving, first confirm you are recording at an acceptable quality level.
BACKGROUND
The higher the recording quality, the more disk space each file uses and the longer it takes to transfer over the internet. The smaller the file, the lower the audio quality – compression reduces definition and clarity. The aim is a sensible balance between the two.
The codec (the software that converts sound to digital data) also affects file size and quality.
Redfish only recommends the Speex codec, at a minimum setting of 27.8 kBit/s, 16.0 kHz, Mono, for audio recordings that will be used for transcription.
1. Setting the Recording Quality in Liberty Meeting Recorder
- Open Liberty Meeting Recorder (LMR).
- Select View > Options from the menu.
- In the Options dialogue, select Recording in the tree on the left.
- In the Sound quality section, click Change. The Sound Selection dialogue opens.
- In the Format drop-down, select the Speex codec.
- In the Attributes drop-down, select 27.8 kBit/s, 16.0 kHz, Mono, Q8. You can select a higher rate if required.
- Click OK, then OK or Apply in the Options dialogue.
2. Test the Result
Make a test recording after changing these settings to confirm the recorded audio quality has improved.
TIPS
Record 2 to 5 minutes of normal conversation at different speech levels to confirm quality holds up through changes in volume.
If you are not sure what to say during the test, read aloud from a past agenda or set of minutes, or from a website on your phone, while in front of the microphone.
If you are still not satisfied with the audio quality, contact Redfish Support or raise a support ticket and we will assist further.
Faults or questions – raise a support ticket with Redfish Technologies.
