Discussion Overview

The discussion revolves around issues related to the IceCream Screen Recorder app on Windows 10, specifically concerning the inability to record microphone sound during a screen video capture. Participants explore potential causes for the problem, methods for recovering or amplifying sound, and the implications of audio encoding formats.

Discussion Character

  • Technical explanation
  • Exploratory
  • Debate/contested

Main Points Raised

  • One participant reports that the microphone was turned on but only at 5% volume during a recording, leading to questions about whether the sound was actually recorded.
  • Another participant suggests that the microphone cable might be faulty and recommends testing the cable by wiggling it while recording.
  • There is mention of the Vorbis audio format used in the recording, with a suggestion that the Opus codec may be a better alternative.
  • A participant expresses skepticism about recovering sound that was not recorded, citing a saying that "information can never be lost" and questioning how to recover sound that was not captured in the file.
  • A humorous response outlines an impractical method of attempting to capture the sound by being far away from the source and traveling faster than sound, emphasizing the absurdity of the situation.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the cause of the recording issue or the feasibility of recovering the sound. Multiple competing views and uncertainties remain regarding the microphone's functionality and the nature of the recording problem.

Contextual Notes

There are unresolved assumptions about the microphone's settings and functionality, as well as the implications of using different audio codecs. The discussion does not clarify whether the sound was recorded at all.

My Windows 10 IceCream Screen Recorder app was not able to record via microphone the sound during a particular screen video capture even if the microphone is turned on (but only 5%). In other instances, the microphone sound is available and also in tests afterwards. I was able to record microphone even if it's only 5%. I don't know what occurred in that particular recording. I got the following result in Mediainfo. Can I recover the sound? I tried opening the *.webm file in Audacity but it can't recognize it. How do I recover the sound, or amplify it? Can any of the following information give one idea whether it is recorded? Audio

Perhaps the microphone cable has a problem; as a test, try recording your voice while wiggling the mic cable and connectors..

A Google search turned up some information:
https://www.google.com/search?&q=playback+for+a_vorbis+encoded

Near the top of the results was this:
Since February 2013, Xiph.Org has stated that the use of Vorbis should be deprecated in favor of the Opus codec, which is also a Xiph.Org Foundation project and also free and open-source.

Good Luck!

It's from a built in mic in the laptop. I think the problem is the volume is zero for the mic.

Is there a way to still recover the sound? There is a saying information can never be lost. So how do you recover a sound that is not recorded in a file at all?

Wellll ... yea.
The process though is rather impractical.

a) Sound - pressure variations of the air
b) Get a working recorder far enough away fast enough that the sound has not yet arrived.
c) Considering that the Earth is surrounded by a vacuum, you are limited somewhere on the Earth
d) Get to the opposite point on the earth (the antipodes), about 12,000 miles away
e) While traveling faster than the sound, you will also have to develop a method to detect and record the darn near non-existent sound you want.

You have 16.66 hours from the time the sound occurred.

Oh well, time to cry in your beer. :cry:
