Music production involves many small, recurring tasks: checking a song’s BPM or key, hearing only the bass in a reference track, trimming an unwanted section from a recording, or balancing the level of an exported track.
You do not have to perform every task in a DAW or paid plugin. Browser tools let you quickly try only the processing you need. Here are Tadaoto’s free tools organized by music production task.
Find a Song’s BPM and Key
The BPM and key analyzer loads an audio file and suggests possible BPM and key values. It is useful for transcribing by ear, remixing, choosing samples, and preparing a DJ mix.
The analysis is not a definitive answer, but a suggestion to confirm by ear. BPM may be reported at half or double the perceived tempo, and key results may be unstable for short recordings or songs with key changes. For detailed instructions, see “How to Find a Song’s BPM and Key.”
Listen to a Reference Track One Part at a Time
The stem splitter separates a finished recording into vocal, drum, bass, and other stems. It is useful when you want to focus on a buried bass line, a drum pattern, or layered backing vocals.
AI separation can introduce missing audio and bleed between parts, so treat separated audio as an aid for transcription and arrangement analysis rather than finished material.
Visualize a Bass Line as MIDI
The bass-to-MIDI converter lets you view hard-to-hear low-frequency movement as MIDI notes. Rather than using it as an answer key after transcribing, watch the MIDI display while listening to the original to narrow down possible notes.
Because the tool may interpret harmonics or a kick drum as bass notes, do not accept every displayed note without checking it on your own instrument or keyboard.
Change the Tempo for Practice
The tempo changer slows down or speeds up a recording while preserving its pitch. It is useful for hearing fast phrases more slowly, practicing a difficult performance in stages, or bringing a loop closer to the tempo of your song.
The pitch shifter moves the pitch in semitone increments while preserving the duration. You can use it to practice a song recorded in a half-step-down tuning with standard tuning, or to fit a sample to the key of your song. Tempo and pitch are separate properties, so choose the appropriate tool for your goal.
Trim the Section You Need from a Long Recording
The audio trimming tool lets you select start and end points on a waveform and save the section you need as a WAV file. You can turn a practice passage, a hummed voice memo, an ambient recording, or a good guitar take into a short asset.
Do not cut off the attack or decay, and add short fades at the edit boundaries. If you only want to remove long gaps before and after the audio automatically, the silence trimming tool is useful.
Convert Audio File Formats
The audio format converter converts WAV, MP3, M4A, FLAC, AIFF, and other files into the format that suits your purpose. WAV is the standard choice for continued editing in a DAW, while MP3 is useful for sharing a smaller review file.
Format conversion does not improve the sound quality of the source. Preserve the original and create separate versions for editing, release, and sharing.
Clean Up Recording Noise and Multiple Assets
The voice noise reduction tool can reduce steady background sounds such as air conditioning, computer fans, and hiss. Heavy processing can also change the character of a voice or instrument, so prioritize natural sound over complete silence.
Use the batch audio finishing tool when you want to process the beginnings and endings, steady noise, and levels of multiple sound effects, voice clips, or instrument assets at once. Always listen after processing to make sure you have not damaged the material’s dynamics.
Create a Seamless Loop
The seamless loop maker uses a crossfade to blend the boundary in background music or ambience and create audio that repeats naturally. It is useful for preparing background audio of an indefinite duration for games, videos, and live streams.
A section containing a prominent melody or a one-time sound effect makes the repetition obvious. Choose a passage with minimal variation and listen through several consecutive loops.
Master a Finished Track
The mastering tool lets you check the loudness and peaks of an exported stereo track and prepare its level for release. It is not a process that fixes every problem in the mix.
If the vocal is inaudible, the low end is too loud, or the track is clipping, return to the mix in your DAW first.
Before and After Using Browser Tools
- Process a copy instead of overwriting the original file
- Check the supported formats, file-size limits, and processing method on each tool page
- Verify analysis results by ear
- Do not publish stems or processed audio from commercial recordings without permission
- Listen to the processed result on both headphones and speakers
Tools do not make decisions for you. They shorten the work of listening, comparing, and refining. When you are ready to finish a track, use the related article “Music Production Checklist: From Finishing a Track to Release.”
