Common browser use cases to test

If everything is too quiet, check volume. If voices are quiet but effects are loud, check the balance. Raising the entire soundtrack also raises effects. Use our device-specific dialogue checklist for the second problem, or the low-volume checklist when the full soundtrack is quiet.

Hearably changes audio from a supported desktop browser tab. It does not control the Netflix TV or mobile app, extract a separate voice track, or repair a missing channel. EQ changes the combined mix; compression responds to its level.

Try Free on the actual title before considering Pro. Protected content, browser versions and output routes can prevent capture or cause playback problems. Stop processing if sound disappears, quality suffers or lip sync changes. A paid plan does not remove these restrictions.

The listening example below lets you compare gain and compression without installing anything. It uses our original text and synthetic speech, not a Netflix recording.

LISTENING EXAMPLE · SYNTHETIC SPEECH

What changes quiet speech and loud effects?

Compare our short original script followed by a generated chime. Start at a low device volume and keep it fixed across all three examples. Each file lasts about five seconds and plays only when you press play.

Spoken transcript: “This is the quiet sentence. A louder chime comes next.” [A chime follows.]

1. Original: quiet speech, louder chime

Listen for the level change after the spoken sentence.

2. Everything raised by 6 dB

Both speech and chime get louder. Their level gap stays the same.

3. Compression plus 6 dB

Speech has the same level as example 2. The following chime is reduced.

In the compressed example, the measured gap between the speech segment and chime drops by 7.4 dB. Speech receives the same gain as in example 2. This is not a measurement of intelligibility.

This is a controlled example with synthetic voices, not a recording from a streaming service or a test of Hearably’s Night Mode. Speech and chime occur in sequence: it does not show voice separation from simultaneous music. Overall levels are deliberately not matched.

Measurements, method and source files

RMS levels from the finished WAV files: the speech window includes its pauses; the chime lasts 0.8 seconds. “Gap” is the difference between those two levels. RMS is not LUFS and does not describe your speakers’ sound pressure level.

Digital segment levels, dBFS RMS
FileSpeechChimeGap
WAV 1-45.2-20.125.0 dB
WAV 2-39.2-14.125.0 dB
WAV 3-39.2-21.517.7 dB

The simple full-band compressor uses a −25 dBFS threshold, 4:1 ratio, instant attack and 150 ms release, followed by +6 dB. No extra normalization, EQ or limiter. Reproduce the processing from the fixed speech files using Node.js.

The English voice was generated with Piper’s LJ Speech model; the German voice uses Thorsten Voice. Their model cards list public domain and CC0 speech datasets respectively. Text, model sources, checksums and settings are documented; no endorsement by the original speakers is implied.

Match the control to the problem

Gain raises speech and effects together. EQ changes frequency balance and can also emphasize unwanted sounds. Compression can reduce level differences between passages, at the cost of changing dynamics. None of these proves that a particular Netflix title is mixed incorrectly.

Netflix’s quiet-voices instructions include a specific Apple TV format check. They do not establish one surround-to-stereo fault across every browser. For supported Apple TV configurations, Apple documents its own dialogue and loud-sound controls. These are device features, not a universal Netflix menu.

Our gain and dialogue explanation shows the arithmetic and the example’s limits. Decide using the same passage on your own output; louder alone does not mean clearer.

Compare your dialogue settings

1

Compare the same short passage

Note the title, episode, timestamp and selected language track. Compare another title at the same device volume before assuming every Netflix stream has the same issue.

2

Check the player and output first

Confirm that Netflix, the browser tab and the operating-system mixer are not muted or unusually low. Confirm which headphones, speakers or display actually receive sound.

3

Use controls for the device you own

A TV or soundbar may offer dialogue or night controls. Use its own manual and restore the original setting if a change makes playback worse. The browser extension cannot change those devices’ app settings.

4

Start Free at a modest setting

Test capture on the actual Netflix title in desktop Chrome or Edge. Compare a small gain change or the Free 3-band EQ with processing off before deciding whether Pro is useful.

5

Compare dynamics only after capture works

Pro includes Night Mode and Voice Boost. Try one change at a time, checking both speech and the next loud moment. An EQ preset does not separate speech from overlapping music.

6

Keep subtitles and a way to undo the change

Subtitles remain useful alongside audio adjustments. Disable processing if playback fails, the tone becomes harsh or audio and video stop lining up.

Built for this exact use case

🔊

Free: up to 120% volume

Make a small per-tab level adjustment on supported capture before deciding whether a larger range is needed.

🎚️

Free: 3-band EQ

Compare basic bass, middle and treble adjustments. The same bands can contain voices, music and effects.

🌙

Pro: dynamics and presets

Night Mode and Voice Boost offer different processing choices. Results depend on the source; they are not dialogue isolation.

🎛️

Pro: 800% range and 10-band EQ

The maximum available setting is not a recommended listening level. Increase gradually and compare with processing off.

Test tab audio in three steps

1

Install

Add Hearably from the Chrome Web Store or Microsoft Edge Add-ons.

→
2

Check playback

Open Hearably on the playing tab and start processing. Confirm that audio still plays before changing settings.

→
3

Compare

Try a small volume or EQ adjustment. Stop processing and reload the tab if playback is disrupted.

Frequently asked questions

Is the Netflix volume booster free?

Hearably Free includes up to 120% volume and a 3-band EQ on supported browser capture. Up to 800%, the 10-band EQ, Night Mode and Voice Boost are Pro features. Test Free on your actual Netflix title first.

Does it work on every Netflix title in Chrome and Edge?

No universal compatibility is promised. Protected-content restrictions, the browser and the output route can prevent capture or change playback. Upgrading to Pro cannot bypass those restrictions.

Can Hearably make only the voices louder?

It processes the combined captured mix. EQ can emphasize frequency ranges and compression can change level differences, but neither extracts an independent dialogue track. Voices and other sounds can overlap.

Can I use it in the Netflix TV or mobile app?

The Chrome and Edge extension controls supported desktop browser tabs. It does not control Netflix’s native TV or mobile apps; use the settings for those devices instead.

Will it fix every surround-to-stereo problem?

No. There is no single loss figure or universal downmix diagnosis for all Netflix playback. Check the track and output configuration; gain and EQ cannot repair a missing channel.

Are the listening examples recordings from Netflix?

No. They use an original Hearably script, synthetic speech and a generated chime. They illustrate a simple full-band compressor, not Hearably’s full processing or protected-playback compatibility.

Test your Netflix tab with Free
