AudioCleanup

Your audio files are full of noise. This app strips it out.

AudioCleanup is a precision audio restoration tool that removes background hiss, hum, clicks, and room echo from recorded audio files directly on your Android device. Whether you are cleaning up a voice memo, a podcast interview, or a field recording, this app gives you granular control over the final sound without requiring a desktop workstation.

Core Audio Restoration Tools

• Adaptive Noise Reduction Engine – Analyzes ambient noise profiles and subtracts them from the signal in real time. Select between three suppression levels: Light, Medium, and Aggressive.
• Click & Pop Remover – Detects and removes transient disturbances (door slams, mic bumps, digital artifacts) while preserving the underlying waveform. Adjustable threshold slider from 0 dB to -60 dB.
• Equalizer with Spectral View – 10-band graphic EQ combined with a real-time spectrogram display. Tap to solo or mute specific frequency ranges (e.g., sub-bass rumble below 40 Hz or high-frequency hiss above 8 kHz).
• De-Esser Module – Targets sibilant frequencies (5 kHz – 10 kHz) with adjustable attack and release times. Apply to voice recordings to reduce harsh 's' and 'sh' sounds.
• Compressor & Limiter – Single-knob compression with ratio control (1:1 to 20:1) plus a brickwall limiter with adjustable ceiling (-0.1 dB to -6 dB). Prevents clipping after noise removal.
• Batch Processing Queue – Load up to 50 audio files (WAV, MP3, FLAC, OGG, M4A) and apply the same restoration preset to all files. Process runs in the background while you browse other apps.

Workflow & User Interface

• Waveform Editor – Pinch-to-zoom waveform display with selection handles for isolating specific segments (e.g., only the noisy silence between sentences). Apply noise reduction to selected regions only.
• Preview A/B Mode – Instantly toggle between original and processed audio without stopping playback. Compare before/after with a single tap.
• Preset Manager – Save custom parameter sets as named presets (e.g., "Studio Voice," "Outdoor Interview," "Vinyl Crackle"). Export presets as .acp files for sharing with other devices.
• Undo/Redo History – Full non-destructive editing history with up to 50 steps. Scroll back through any change made during the session.

Supported Audio Formats & Export Options

• Input – WAV (16/24/32-bit), MP3 (up to 320 kbps), FLAC (up to 24-bit/96 kHz), OGG Vorbis, M4A (AAC), and raw PCM.
• Output – WAV (16/24/32-bit float), MP3 (128-320 kbps), FLAC (lossless), and OGG. Select sample rate (44.1 kHz, 48 kHz, 96 kHz) and bit depth.
• Destination – Save directly to device storage, SD card, or share via system share sheet (email, cloud storage, messaging apps).

Key Advantages

• Offline processing – no internet connection required for any restoration or export operation.
• Low-latency preview (under 100 ms) for real-time parameter adjustment.
• No file size limit – process recordings longer than one hour without splitting.
• Supports Android 4.1 and above, including older devices with limited RAM.

Heads up: you'll need wifi for initial download and for accessing the in-app help videos. The spectrogram view and batch processing are free; the de-esser and preset export require a one-time in-app purchase.
