Is there a way to lower the recording volume of HTML5 recording to prevent feedback?

Question

I am using Recorder.js to record audio but there is terrible feedback if I don't use a headset. There is even a little feedback if I use my apple earphones where the mic is a bit closer to the ear piece. Is there a way to lower the mic/recording volume and prevent the feedback?

Answer 1

Their example page (example_simple_exportwav.html) states that you should wear headphones or turn down the volume.

Also before you enable microphone input either plug in headphones or turn the volume down if you want to avoid ear splitting feedback!

You could mute or decrease the volume of the speakers during recording:

• Muting a HTML5 audio element using a custom button
• How to mute all sound in a page with JS?
• How to set the loudness of HTML5 audio?

I also tested a few examples and never experienced feedback with my laptop speakers. Could you post your code so we could test it live?
