## What do you want to work on?

Choose your workflow for the relevant guide and a checklist for your workflow.

**Checklists and guides**

**Use Sound Boost for the first time**

Activate Sound Boost in the tab you want, adjust the volume and deliberately stop processing again.

[Open workflow and template](https://soundboost.impulse-apps.de/en/guides/getting-started/#practice)

**Adjust volume from 0 to 1000 percent**

Use the Sound Boost slider and understand how tab volume, source audio and device volume work together.

[Open workflow and template](https://soundboost.impulse-apps.de/en/guides/adjust-volume/#practice)

**Choose presets and return to a baseline**

Distinguish free volume presets from Plus sound profiles and compare changes clearly.

[Open workflow and template](https://soundboost.impulse-apps.de/en/guides/presets-and-reset/#practice)

**Control tabs individually and keep an overview**

Understand the Plus tab overview: independent audio channels, mute, play/pause and the activation each tab requires.

[Open workflow and template](https://soundboost.impulse-apps.de/en/guides/control-tabs/#practice)

**Adjust the 10-band equalizer deliberately**

Bass, mids, treble and preamp in the Sound Boost Plus mixer: small changes, neutral comparisons and gain reserve.

[Open workflow and template](https://soundboost.impulse-apps.de/en/guides/understand-the-equalizer/#practice)

**Use balance and mono in the Plus mixer**

Understand left and right channels, test balance and deliberately listen to stereo in mono.

[Open workflow and template](https://soundboost.impulse-apps.de/en/guides/balance-and-mono/#practice)

**Compressor, headroom and output protection**

Understand Sound Boost’s shared output protection and why a limited peak does not mean a repaired source.

[Open workflow and template](https://soundboost.impulse-apps.de/en/guides/output-protection/#practice)

**Control Sound Boost with keyboard shortcuts**

Use Alt+Shift+B to toggle processing and customise the shortcut through the browser’s existing controls.

[Open workflow and template](https://soundboost.impulse-apps.de/en/guides/keyboard-shortcuts/#practice)

**Browser permissions and local audio data**

Why Sound Boost needs activeTab, audio capture and tab data, and when you need to activate a tab again.

[Open workflow and template](https://soundboost.impulse-apps.de/en/guides/browser-permissions/#practice)

**No audio or no player control?**

Check the source, mute state, audio output, tab activation and browser limits when Sound Boost behaves unexpectedly.

[Open workflow and template](https://soundboost.impulse-apps.de/en/guides/no-audio/#practice)

**Understand free features and Plus**

What Sound Boost offers for free, which mixer features need Plus and why sales remain disabled.

[Open workflow and template](https://soundboost.impulse-apps.de/en/guides/free-and-plus/#practice)

**Understand quiet speech in lectures and videos**

Adjust quiet browser speech gradually and distinguish intelligibility, gain and optional Plus EQ.

[Open workflow and template](https://soundboost.impulse-apps.de/en/guides/understand-quiet-speech/#practice)

**Understand noise and poor recordings**

Recognise when gain raises background noise and when a better source is needed instead of more settings.

[Open workflow and template](https://soundboost.impulse-apps.de/en/guides/noise-and-poor-source-audio/#practice)

**Diagnose distortion, crackling and harsh sound**

Compare distorted browser sound with and without Sound Boost and inspect gain, EQ and output device separately.

[Open workflow and template](https://soundboost.impulse-apps.de/en/guides/diagnose-distortion/#practice)

**Switch deliberately between audio tabs in Free**

Switch the Free Sound Boost single channel and check which previous players continue unprocessed.

[Open workflow and template](https://soundboost.impulse-apps.de/en/guides/switch-tabs-in-free/#practice)

**Continue after navigation, sleeping tabs or restart**

Check Sound Boost channels after domain changes, sleeping tabs and browser restarts and deliberately reactivate.

[Open workflow and template](https://soundboost.impulse-apps.de/en/guides/navigation-and-browser-restart/#practice)

**Play and pause normal and specialised players**

Distinguish audible tab audio from optional Plus playback controls and use the website player when limited.

[Open workflow and template](https://soundboost.impulse-apps.de/en/guides/play-pause-and-custom-players/#practice)

**Distinguish pause, mute, zero percent and Power**

Choose between player pause, browser mute, zero gain and Power off and check actual playback state.

[Open workflow and template](https://soundboost.impulse-apps.de/en/guides/pause-mute-zero-and-power/#practice)

**Diagnose one-sided headphone audio**

Check one-sided browser audio with original and comparison sources and understand balance and mono as optional Plus tools.

[Open workflow and template](https://soundboost.impulse-apps.de/en/guides/one-sided-audio-and-headphones/#practice)

**Evaluate settings with a fair listening comparison**

Compare Sound Boost settings using the same passage, similar loudness and a concrete listening goal.

[Open workflow and template](https://soundboost.impulse-apps.de/en/guides/compare-settings-fairly/#practice)

**Describe an audio issue clearly for support**

Create a concrete Sound Boost issue description with browser, channel state, reproducible passage and private data removed.
