Increase the Amplitude of Low Frequencies - Recording

Audacity Help Forum Windows
1

Hi all,
Today I tried to record the sound output from my Keyboard to Mic input of laptop and I found

  1. The Lower Notes (frequencies) Like C and D have lesser amplitude than higher notes after being recorded :frowning: . How can I increase the amplitude of Lower frequencies?

  2. Also when I play my Keyborad using Sustain effect the sound actually fades for 5 seconds, but the audacity records the sound only for 3 seconds and the last 2 seconds were silence :open_mouth: - Meaning the audacity is clipping out the sound once its reaches a low amplitude threshold. How to fully record the sound diminishing until zero?

I assume that audacity has a minimum threshold for recording frequencies and amplitude, how do I change them? :confused:

Please help! and Thanks!

That doesn’t usually work. You need a Stereo Line-In on the computer (blue socket) or a USB adapter to provide those connections like this:

That’s my Behringer UCA202. Other people make adapters.

Some laptops have the ability to switch one connection between Stereo-Line and Mono-Microphone consult your instructions, but most don’t.

Then you go into Windows Control Panels and turn off Enhanced Services and any other conferencing tools you can find.

Thank you Koz,

I will try to tweak my soundcard settings as per your latter suggestion, however I am trying to understand your first part.
Thanks again!

By the way, How to change the threshold settings?

No, it doesn’t. It records dead flat from 0dB down to the limits of audibility -96dB and all audio frequencies. Windows, however, has problems. Audacity can only use whatever the computer gives it, and the computer has ideas and settings.

Mic-In on a laptop computer is designed to accept a mono microphone.

And only a mono microphone (or headset). It’s not a general stereo audio input like computers used to have. To get a connection for your keyboard, you need the usually missing blue connection like on this PC Desktop sound card.

Or a USB stereo adapter like I posted earlier. I have two keyboards and I connect the stereo headphone out of each keyboard to the stereo in of my computer, or one of those USB adapters.

Mic-In is mono, not stereo and it has serious overload and distortion issues.
