Installation & Usage Guide
Step‑by‑Step Installation
Downloading Smart Gain is straightforward. Visit the official website, click the “Download for Windows” (or macOS, Android, iOS) button, and save the installer file. Run the executable on Windows or the .dmg on macOS; the wizard will guide you through the standard acceptance of the license agreement, selection of the install folder, and creation of a desktop shortcut. On mobile devices, tap the App Store or Google Play link, and the app will install automatically.
After installation, launch Smart Gain. The first launch may prompt you to allow access to your media library – this permission is required for the app to locate and open audio files.
How to Normalize Audio
1. Click “Add File” or drag‑and‑drop your media into the main window.
2. The waveform appears, and Smart Gain automatically calculates the optimal target loudness.
3.
Press “Normalize” to apply the gain. The waveform updates instantly, showing the new amplitude levels.
4. Save the file by choosing “Export” – the original file remains untouched, and the normalized version is saved with a suffix “_normalized”.
Manual Amplification
If you need to boost a specific segment, select the region on the waveform, then use the “Gain Slider” or type a decibel value in the “Custom Gain” box. Click “Apply” and watch the selected portion rise to the desired level while the rest of the track stays unchanged. This feature is ideal for improving whispered speech or enhancing quiet musical passages without affecting the overall balance.
Compatibility
Smart Gain runs on Windows 10 or later, macOS 10.14 (Mojave) and newer, Android 8.0+, and iOS 13+. The application uses standard audio codecs, so any device that can play MP3, WAV, AAC, FLAC, or OGG will be fully compatible.
