Analyze and cut audio files using Audacity/Audition to remove extra silence or noise.
Budget: $30 – $250 USD
We'll provide 1800 audio files into a Drive folder.
All recordings say "Hey Tesla".
You need to hear each audio and evaluate if it contains noise.
The acceptable background noise is maximum -40dB
If the noise is for example -30dB and its position is during the phrase, add the prefix "unusable-" at the beginning of the file name, for example: "unusable-[fileName.wav]"
In the case that the noise is before or after the phrase, remove it by cutting this segment of the audio file. Also, remove extra silence.
The final version of your audio file must be:
(~1-second silence | "Hey Tesla" | ~1-second silence)
*Note that 1 second is just an approximation, it can be a little bit more or a little bit less, just make sure you removed noise and the phrase has not been compromised.
Once you're done editing it. Export the file with these settings:
- WAV format
- 16kHz
- 16 bit
Then upload the result to the "Edited" sub-folder in the provided link.
For a better understanding of the noise conditions, check the 3 samples provided.
