A podcast or YouTube voice-over rarely gets finished with a single tool. You need to reduce noise, cut what you don't need, join several recordings and match the volume before it sounds good. This guide shows how to chain our tools into one editing workflow.
The whole workflow at a glance
- Record: record with your mic or prepare an existing file.
- Remove noise: reduce background noise.
- Cut: remove mistakes and long pauses.
- Merge: join segments or episodes into one file.
- Match loudness: bring the overall volume to a comfortable level.
Step 1. Record
Record with the Online Voice Recorder or use a file from your phone's recorder app. Record somewhere quiet and keep the same distance between mouth and mic; editing gets much easier.
Step 2. Reduce noise
Add the recording to the Voice Noise Remover and adjust the strength. Start at 100% and lower it if the voice sounds unnatural. The tool is built for human voices, so it is not suited to recordings with background music.
Step 3. Cut what you don't need
The Online Audio Editor lets you cut, silence sections and shorten silent gaps on one screen. Select flubs or long pauses and delete or silence them. If you only need to trim the start and end, the MP3 Cutter is enough.
Step 4. Join recordings
If you recorded the intro, main part, ads and outro separately, set the order in Merge MP3 Files and join them. If the transitions feel abrupt, add about 1 second of crossfade.
Step 5. Match loudness
Run the merged file through Increase Volume & Normalize and apply average loudness matching (about -16 dB). If parts were recorded very quietly, apply peak normalization (peak -1 dB) first, then match the average.
Finish: choose a save format
For podcast platforms, MP3 at 128 to 192 kbps is usually enough. If you plan more editing, save a WAV to avoid quality loss. If you need a script, use the Audio to Text Converter for episode descriptions or subtitles.
Common problems
- Not sure about the order: denoise → cut → merge → loudness works for most cases. If the files to merge differ a lot in volume, match each one first.
- Repeating the same settings every time: FreeSoundTools does not remember your settings, so note your favorites (for example MP3 192 kbps, -16 dB).
- Many files take a long time: everything runs in your browser, so speed depends on your device. Process files in batches if you are not in a hurry.

Frequently asked questions
Do I have to follow this order?
Denoise → cut → merge → loudness is the safest default, but you can change it depending on your recording.
Do I need every step?
No. Skip noise removal for clean recordings and skip merging if you only have one file.
Can I process several files at once?
Each tool handles one job at a time (merge takes multiple files). Clean up each recording, then merge at the end.
Are my files kept on a server?
No. All tools run in your browser; files are not uploaded.
Should I denoise an intro with music?
Not recommended. The noise remover is built for voices and can eat into music. Apply it only to voice sections.
