## Overview

Applies a deterministic listening-assistance chain: it removes low rumble, gently emphasizes speech presence, reduces steady broadband noise, and limits peaks. It is not a calibrated hearing aid or a medical device, and it cannot replace individualized hearing care.

## Inputs

- **Audio File** (file): Select audio to enhance
- **Enhancement Strength** (select)
- **Output Format** (select)

## When to use

- When listening to voice recordings with distracting low-frequency background rumble.
- When preparing audio files for individuals who benefit from enhanced speech presence and controlled peak volumes.
- When you need to clean up steady broadband noise from voice memos without using complex audio editing software.

## How it works

- Upload your audio file in any standard format up to the 100 MB limit.
- Select the enhancement strength from gentle, balanced, or strong to control the level of noise reduction and speech EQ.
- Choose your preferred output format, such as MP3, WAV, FLAC, M4A, or OGG.
- Process the file to apply the low-frequency cleanup, speech-presence EQ, and peak limiting, then download the enhanced audio.

## Use cases

- Enhancing recorded university lectures to make the professor's voice easier to understand.
- Cleaning up voice memos recorded in noisy environments with low-frequency HVAC hum.
- Preparing accessible audio materials for students or colleagues who require clearer speech presence.

## Frequently asked questions

### Is this tool a replacement for a medical hearing aid?

No, this is an audio processing utility and not a medical device or a calibrated hearing aid.

### What audio formats does the tool support?

You can upload standard audio files and export the enhanced output as MP3, WAV, FLAC, M4A, or OGG.

### How does the enhancement strength setting work?

It adjusts the intensity of the speech EQ and noise reduction, offering gentle, balanced, or strong processing options.

### Does this tool remove sudden loud noises?

It includes peak limiting to protect against sudden volume spikes, though it focuses primarily on steady broadband noise.

### Is there a file size limit for uploads?

Yes, the tool supports audio file uploads up to 100 MB.
