Updated for Windows 11 and Windows 10. Windows Sound Recorder is useful for quick microphone recordings, but many people need more: recording the sound playing through the PC, choosing a microphone or line-in source, removing silent sections, editing the result, and exporting it to a common audio format.
This guide explains how to record computer audio on Windows 11 or Windows 10 and shows the complete workflow in Cool Record Edit Pro.

What type of audio do you want to record?
Choose the recording source before you begin. The three common options are:
- Microphone: your voice, an interview, a lecture, or an instrument connected to the PC.
- System audio or Stereo Mix: sound played by a browser, media player, meeting app, or another Windows program.
- Line-in: audio from an external cassette player, record player with the correct preamp, CD player, mixer, or another device.
Windows 11 Sound Recorder is a good choice for a simple microphone recording. A desktop recorder/editor is more practical when you also need to select system sound, edit the waveform, apply effects, or save in a particular format.
| Task | Windows Sound Recorder | Cool Record Edit Pro |
|---|---|---|
| Record a microphone | Yes | Yes |
| Select Stereo Mix or line-in | Limited by Windows/device setup | Yes, when the input is available |
| Edit the recorded waveform | Basic trimming | Full waveform editor |
| Apply audio effects | No | Yes |
| Schedule or skip silence | No | Yes |
How to record computer audio on Windows 11/10
Save your work in other audio programs and close any app that might take exclusive control of the sound device. If you are recording a conversation, meeting, broadcast, or copyrighted material, obtain permission and follow the laws and terms that apply where you live.
Step 1: Install and open the audio recorder
Download Cool Record Edit Pro from the official website, run the installer, and open the program. It supports Windows 11 and Windows 10.
Click New Record. Choose the sample rate and channel setting, then click OK. For spoken voice, mono is often enough; for music or computer playback, stereo is normally the better choice.

Step 2: Select the correct recording source
Choose your sound card and input source:
- Select Microphone to record your voice or an acoustic instrument.
- Select Stereo Mix, What U Hear, or a similarly named loopback input to record sound playing through the computer.
- Select Line In for an external audio device connected to the line-in socket.

What if Stereo Mix is missing?
- Right-click the speaker icon in the Windows taskbar and open Sound settings.
- Open More sound settings, then select the Recording tab.
- Right-click an empty area and enable Show Disabled Devices.
- If Stereo Mix appears, right-click it and choose Enable.
- If it is still unavailable, install the current audio driver from the PC or sound-card manufacturer.
Not every audio device exposes Stereo Mix. Its availability depends on the hardware and driver. Do not select a source that you cannot test: play a short sound and watch the input level meter before starting the real recording.
Step 3: Choose recording options
Use Timer Record if you want recording to start or stop at a specified time. Enable the option to record without silence when you want to reduce long quiet sections, such as during a web radio program or a spoken presentation.

Before recording a long session, make a 10-second test. Listen for distortion, echo, background noise, or a source that is too quiet. If the waveform reaches the top and bottom of the display repeatedly, reduce the input level to avoid clipping.
Step 4: Start, stop, and keep the recording
Start playing the audio you want to capture, then click Record. The level meter and waveform should respond immediately. When you finish, click Pause or Stop, then choose Keep to send the recording to the audio editor.

Step 5: Edit and export the audio
In the waveform editor, select unwanted silence or mistakes and remove them. You can also adjust volume, add a fade-in or fade-out, and apply other effects. Keep an untouched copy of the original recording before making major edits.
Choose File > Save File As and select the output folder and format. WAV is useful when you want an uncompressed editing master; MP3 is smaller and convenient for sharing. For more editing details, read how to edit audio files and how to add audio effects.
Recommended settings for common recordings
| Recording | Source | Suggested starting point |
|---|---|---|
| Voice note or interview | Microphone | Mono, moderate input level |
| Music or browser playback | Stereo Mix/system input | Stereo, test for clipping |
| Cassette or external player | Line-in | Stereo, adjust output and input levels |
| Long spoken program | Microphone or line-in | Test timer and silence options first |
Troubleshooting
The recording is silent
Confirm that the selected input is the one whose level meter moves. Check Windows privacy settings for microphone access, unmute the device, and make sure another application is not using it exclusively.
The audio is distorted or crackling
Reduce the recording level, turn off unnecessary Windows audio enhancements, try another sample rate, and install the latest manufacturer audio driver. Make a short test after each change.
The recording contains an echo
If you are recording system audio, do not also capture the same sound through an open microphone. Use headphones or mute the microphone unless narration is required.
The saved file is too large
Keep a WAV master if you plan to edit again, then export a separate MP3 copy for sharing. A compressed file is smaller, but repeated conversion can reduce quality.
Frequently asked questions
Can Windows 11 record audio without extra software?
Yes. Windows Sound Recorder can make straightforward recordings from an available input, especially a microphone. A dedicated audio recorder/editor is useful when you need system-audio source selection, waveform editing, effects, scheduling, or more export control.
Can I record the sound playing on my computer?
Yes, when your sound device provides a system-audio input such as Stereo Mix or What U Hear. Select that source in the recorder and test the level meter. Availability depends on the computer’s audio hardware and driver.
Does Cool Record Edit Pro support Windows 11?
Yes. The current download supports Windows 11 and Windows 10.
Can I record microphone and system audio together?
This depends on the input routing exposed by your sound device. Some drivers provide a combined source; others require a virtual mixer or separate recordings. Always make a short test before an important session.
Is the download free?
The installer is available as a free trial. A paid license removes trial limitations; see the upgrade options for current details.
Start recording and editing
For the best result, identify the correct source, make a short level test, record the session, keep an original copy, and export a separate file for sharing. This workflow helps prevent silent recordings, clipping, and accidental loss.
