Best when a recording is plainly too quiet on phones or speakers. Use 150% when you want the same common default used by many online boosters, or a stronger dB lift for very quiet speech. Use Audio Normalizer instead when you want several files aligned to one safe output level.
Choose the voice note, old recording, lecture, podcast, or audiobook that is hard to hear on phones, speakers, or headphones.
Start with a moderate boost. Increase it only if the preview is still too quiet, because too much gain can make distortion obvious.
Turn on speech leveling for spoken recordings where the speaker moves closer and farther from the microphone.
Use Prepare preview first for important files, then click Boost volume and download when the listening level feels comfortable.
Raise a quiet audiobook, podcast, or lecture before copying it to a phone, speaker, or simple MP3 player.
Result preview: A quiet audiobook, podcast, or lesson becomes louder and easier to follow on a phone, speaker, or simple MP3 player.
Use speech leveling when a narrator moves closer and farther from the microphone during the same recording.
Result preview: Speech that moves closer and farther from the microphone becomes easier to listen to without constant volume changes.
Boost a recording that was saved too quietly from a browser, meeting app, cassette transfer, or old lecture file.
Result preview: A browser, meeting, cassette, or lecture recording that was saved too quietly gets a stronger listening copy.
Create a louder listening copy while keeping the original audio file unchanged.

Checked against mature online audio tools for the same job: the goal is not only to complete the task, but to make the next decision obvious.
Mature cleanup tools offer presets, before-and-after thinking, safety warnings, and clear export choices for voice, music, audiobooks, or old recordings.
Many one-click cleanup tools hide what changed, so users cannot tell whether a setting is too aggressive.
Cinch frames each cleanup around listening comfort, original-file safety, practical next steps, and clear result previews that reduce overprocessing.
Use it when you already have an audio file and need a cleaner, smaller, clearer, or easier-to-share copy before opening a full audio editor. It is useful for lecture recordings, meeting audio, voice notes, podcasts, music clips, MP3 files, WAV files, and saved browser recordings.
Yes. This browser-based audio tool is designed to process the file locally, so you can test settings, preview the result, and download a new copy without uploading private recordings to a server.
Common browser-supported formats such as MP3, WAV, M4A, AAC, OGG, and FLAC usually work best. Very large files, unusual codecs, or protected streaming files may need to be converted, trimmed, or recorded again first.
Preview the result, compare it with the original, and make sure the speech, music, timing, volume, file size, or metadata still feels right. If the setting is too strong, choose a gentler option and run the audio processing step again.
