User Guide¶

Welcome to the user guide for the Flat Equalizer app! This guide will walk you through how to make the most of the app's features to enhance your audio experience on Android devices.

Equalizer¶

The Equalizer is a powerful tool that lets you fine-tune your audio to suit your preferences. It provides a range of adjustments, allowing you to modify different frequencies in your music. You can adjust up to 10 bands (limited to 5 bands on Android 8 and below). Each slider corresponds to a specific frequency range. Here's how to use it:

Balance Frequencies: If your music sounds uneven, you can use the sliders to balance the different frequencies. Move the sliders up or down to adjust the bass, midrange, and treble.
Enhance Bass and Treble: Boosting the lower frequencies (bass) can give your music a deeper and more thumping feel. Boosting the higher frequencies (treble) adds more sparkle and clarity.
Presets: Choose from various presets designed for different types of music, like classical, hip-hop, or rock. If you're unsure where to start, these presets can be a great help.

Bass Boost¶

Activate the Bass Boost effect to make the low-end frequencies in your music more pronounced. This adds a satisfying rumble and depth to your listening experience.

Loudness¶

The Loudness effect increases the overall volume of your music. It can make your tracks sound more impactful, but be careful not to set it too high, as it may cause distortion or discomfort.

Virtualizer¶

Immerse yourself in your music with the Virtualizer effect. It makes the sound feel more spacious, creating a sense that the audio is coming from various directions.

Reverberation¶

The Reverberation effect adds a sense of space to your music, making it feel like you're listening in a larger room. You can choose different room sizes to match your preference.

Channel Balance¶

Adjust the volume balance between the left and right audio channels. This feature is handy if you're not sitting in the center of your speakers or if your headphones have differences in volume between the left and right sides. It can also help prevent volume fluctuations caused by certain phones' limiters.

Channel Gain: Use this setting to fine-tune the balance between the left and right channels.

Remember, the key to a great audio experience is experimentation. Try different settings and combinations to find what sounds best to you. Feel free to explore and adjust until you achieve the desired sound quality.

Profiles¶

Profiles are like customized sound settings that you can save and switch between whenever you want. Imagine you're using your car's Bluetooth system – you'd probably prefer a different sound style compared to when you're using your Bluetooth headphones. With profiles, you can easily save these different settings.

You can create a new profile by tapping the "New profile" button at the bottom or by selecting "Save As Profile" from the 3-dot menu. Each profile can be set to activate automatically based on the device you're using. For example, if you have a specific profile for your car's Bluetooth, it will be automatically applied when you connect to it.

Once a profile is applied automatically, it will stay active even if you disconnect the device. It will only change if you have another profile set to automatically apply for a different device, like "Speaker." This means that once you switch to a profile using the auto-apply feature, it'll stay that way until another auto-apply profile takes over, or you manually apply a different profile.

If you wish to disable all equalizer effects upon disconnecting your Bluetooth device or headphones, follow these steps:

Create a new profile with all effects turned off.
Configure this profile to automatically apply when connected to a 'Speaker.' This will ensure that no effects are active when your Bluetooth device or headphones are not in use.

However, please be aware of the following implications:

Disabling all effects will halt the Equalizer background service to improve battery life.
Consequently, the auto-apply feature will also become inactive, requiring manual intervention to apply the settings again.
To address this, consider enabling only the bass boost effect and setting it to 0%. This approach will keep the service active and maintain the functionality of the auto-apply feature.

You can also share your profiles with friends and family. Just tap the bottom profile button and select "Share Profile." It'll generate a link to share with them. When they tap on the link, your profile will be applied to their device.

This way, you can have different sound setups for different situations and devices, making your audio experience exactly how you want it.
