Zoom Volume Booster for Browser Meetings
Test incoming Zoom audio with Free up to 120% and a 3-band EQ in Chrome or Edge.
Chrome & Edge · Local audio processing
A Zoom volume booster can raise incoming audio in a supported browser tab. First check whether one participant, every voice or the entire device is too quiet. Hearably changes the meeting audio you hear; it does not change your microphone or the sound received by other participants.
Use the checklist below before installing. If you need to diagnose missing sound, echo or a microphone problem in more detail, follow the Zoom audio troubleshooting guide.
Which Zoom audio problem are you hearing?
| Symptom | Check first | Will a volume booster help? |
|---|---|---|
| No sound, including the speaker test | Selected output, site mute and system volume | Restore ordinary playback first. Gain cannot fix a disconnected output. |
| Every participant is audible but quiet | Zoom output, browser mixer and headset volume | Modest tab gain may help if playback works and capture is supported. |
| Only one participant is quiet | Ask them to check their microphone and position | Tab gain also raises the other voices. It is not a separate participant control. |
| Others cannot hear you | Your microphone selection, mute and permissions | No. Incoming playback processing does not change your outgoing microphone. |
| Echo or feedback | Duplicate audio connections and sound returning into a microphone | Extra gain may worsen it. Resolve the feedback path first. |
| Robotic voices or missing words | Connection, device load and whether others hear the same problem | No. More volume does not recover missing audio. |
Check Zoom's output before boosting it
- In the Zoom Web App, open Settings → Audio. Select the intended speaker and use Test Speaker, as described in Zoom's Web App settings guide.
- Check the browser and operating-system output level, the tab's mute state and any physical headset control. Compare another audio source through the same output. If that is also quiet, use the laptop audio checklist.
- Compare two participants. If only one is quiet, ask that person to check their input. If you joined audio by telephone, the sound is outside the browser tab.
- For echo, check for duplicate computer/telephone connections or nearby devices. Zoom's echo guidance explains why an extra audio connection can remain a problem even with its microphone muted.
What is free, and what does Pro add?
Hearably Free includes up to 120% gain and a 3-band EQ. Use it to test your actual meeting route in desktop Chrome or Edge. Pro adds up to 800% gain, a 10-band EQ, Voice Boost and Night Mode. See the plan comparison. An upgrade does not make an unsupported meeting or output route compatible.
Compare a short phrase before your next meeting
- Use a test conversation with a willing colleague. Keep the same speaker, headset and device volume for each comparison; no meeting recording is needed.
- Enable Hearably on the meeting tab and confirm that sound continues. Begin with flat EQ and 100% gain, then compare a small increase up to Free's 120%.
- Have the person repeat the same phrase. Compare the original, the adjustment and the original again. Check an ordinary louder voice too, so a setting chosen for a quiet speaker does not make the rest uncomfortable.
- Only then try a small EQ adjustment. A louder voice is not necessarily clearer, and boosting treble can also emphasize hiss or clicks.
- Turn enhancement off and confirm that normal meeting audio returns. Test again after changing your output device or rejoining.
If sound disappears after enabling: turn enhancement off first. Recheck Zoom's selected output; if needed, leave and rejoin the meeting or reload the tab when you can do so without interrupting the call. If native playback works but enhancement does not, keep it off for that session. The Edge setup guide covers browser installation and recovery.

What can change in a mixed meeting signal?
Hearably receives supported tab playback after the meeting has delivered it to your browser. That signal may contain several voices and shared audio together. A gain control raises the mix; EQ changes its frequency balance. Neither gives Hearably a separate track for each participant.
Speech-focused EQ may make some voices easier to follow, but it cannot restore consonants removed at the source or separate overlapping speakers. Dynamics processing can change level variation in the captured mix; it does not replace Zoom's microphone processing or guarantee equal loudness between people.
The Zoom desktop and mobile apps, telephone audio and other applications are outside this browser-tab route. Use Zoom's desktop and mobile audio-testing instructions for those apps. For a wider diagnosis, see what can improve Zoom audio quality.
Keep Zoom listening adjustments easy to compare
Keep the output fixed
Compare the same headset or speakers. A Bluetooth or device switch changes the route and needs another check.
Separate one voice from the whole meeting
A quiet participant needs an input check. Raising the tab also raises everyone else.
Change one control at a time
Start with gain, then compare a small EQ change. Keep the original available for a useful comparison.
Keep a working fallback
Confirm that turning enhancement off restores normal meeting audio before relying on it in a call.
Use allowed browser extensions
On a managed work or school device, follow the extension policy. Store availability does not mean installation is permitted.
Keep captions available
Use the meeting’s available caption options when helpful. More playback volume does not recover every unclear word.

Frequently asked questions
How do I make Zoom louder in Chrome or Edge?
Check the Zoom Web App speaker output, browser and system volume first. If supported incoming tab audio remains quiet, compare Hearably Free at 100% and up to 120% with a flat EQ. Keep the same output device during the test.
Is the Zoom volume booster free?
Hearably Free includes up to 120% gain and a 3-band EQ. Pro adds up to 800%, a 10-band EQ, Voice Boost and Night Mode. Test Free before upgrading; payment does not remove capture restrictions.
Can I boost just one Zoom participant?
Hearably adjusts the captured tab mix, not a separate participant track. Raising gain can raise every audible participant and shared sound. Ask the quiet person to check their microphone first.
Will other participants hear my microphone louder?
No. Hearably processes incoming browser playback. Use Zoom’s microphone selection, mute and input settings to troubleshoot what others hear from you.
Does it work with the Zoom desktop app or telephone audio?
No. This page covers supported Zoom Web App audio in desktop Chrome or Edge. Native apps and audio joined by telephone are outside the tab’s playback path.
Why did Zoom become silent after I enabled enhancement?
The browser, meeting or output route may not support the current capture path. Turn enhancement off, confirm the selected output and restore normal playback. If needed, rejoin or reload at a suitable moment. Keep enhancement off if the problem returns.
Can more volume fix echo, dropouts or robotic speech?
No. Resolve the feedback, connection or source problem first. Extra gain can make existing artifacts louder and does not reconstruct missing speech.
Can I use it on a work or school computer?
Only if the organization permits the extension and tab-audio capture. Test the actual browser, meeting and output before relying on it. No administrative-policy or meeting-compatibility guarantee is implied.
