Editing an audio file does not always require expensive music software or a complicated digital audio workstation.

RouteNote Convert offers a growing collection of free online audio tools that can convert, edit, analyse and transform audio files directly from your web browser.

Whether you need to convert a WAV file to MP3, remove vocals from a song, detect its BPM or quickly trim a recording, RouteNote Convert provides a simple tool designed for the job.

The platform currently includes more than 40 audio-focused conversion routes, effects and utilities covering popular formats such as MP3, WAV, FLAC, AIFF, AAC and OGG.

What is RouteNote Convert?

RouteNote Convert is a collection of easy-to-use online tools for audio, video, image, document and font files.

Its audio section is particularly useful for musicians, producers, podcasters, video creators and anyone who needs to make a quick change to an audio file without installing specialist software.

Users can choose the tool they need, upload or drag and drop their file, apply the required conversion or effect and download the processed result.

Convert Audio Files Online

RouteNote Convert includes 20 different audio conversion options across five widely used formats:

  • MP3
  • WAV
  • FLAC
  • AIFF
  • AAC

You can convert each supported format into one of the other available formats. This includes popular tools such as WAV to MP3, MP3 to WAV, FLAC to MP3, WAV to FLAC, AIFF to WAV and AAC to MP3.

MP3 converters

MP3 is one of the most widely supported compressed audio formats. Its relatively small file size makes it useful for sharing music, podcasts, voice recordings and other audio online.

RouteNote Convert allows you to convert MP3 files into WAV, FLAC, AIFF or AAC.

WAV converters

WAV files are commonly used for high-quality audio production and mastering. They can provide excellent audio quality but are normally much larger than compressed formats such as MP3 or AAC.

RouteNote Convert can convert WAV files into MP3, FLAC, AIFF or AAC.

FLAC converters

FLAC uses lossless compression, reducing the size of an audio file without discarding audio data in the same way as a lossy format.

You can use RouteNote Convert to change a FLAC file into MP3, WAV, AIFF or AAC.

AIFF converters

AIFF is an uncompressed audio format originally developed by Apple. It is frequently used for high-quality recordings and professional audio production.

RouteNote Convert supports AIFF conversions to MP3, FLAC, WAV and AAC.

AAC converters

AAC is a compressed format commonly used by mobile devices, streaming platforms and digital media applications.

AAC files can be converted into MP3, FLAC, AIFF or WAV using RouteNote Convert.

Remove Vocals From a Song

The RouteNote Convert Vocal Remover can separate or reduce the vocal element of a song to help create an instrumental or karaoke-style version.

Upload an MP3, FLAC or WAV file and the tool will process the recording. Files of up to 200MB are supported.

A vocal remover can be useful for:

  • Creating karaoke tracks
  • Practising a vocal performance
  • Studying an instrumental arrangement
  • Preparing reference material
  • Experimenting with remixes

Results can vary depending on how the original song was mixed, particularly when vocals and instruments occupy similar parts of the stereo field.

Make sure you have permission from the relevant rights holders before publicly releasing or commercially using an edited version of someone else’s recording.

Reduce Background Noise

Unwanted noise can make voice recordings, podcasts and music demos harder to hear.

The RouteNote Convert Noise Reducer is designed to reduce background noise from MP3, FLAC and WAV recordings. The tool supports audio files of up to 200MB.

It can be useful when working with recordings containing:

  • Background hiss
  • Room noise
  • Fan or computer noise
  • Low-level environmental sounds
  • Noise from basic recording equipment

Noise reduction cannot always repair a badly distorted or heavily contaminated recording, but it can help improve the clarity of otherwise usable audio.

Trim and Cut Audio Files

The free Audio Trimmer lets you select and keep a specific section of an MP3, FLAC or WAV file.

After uploading a file, you can move and resize the selected region to choose the exact part of the recording you want to retain. The tool supports uploads of up to 200MB.

An online audio cutter is useful for quickly:

  • Removing silence
  • Cutting a recording down to length
  • Extracting a short audio clip
  • Creating a ringtone
  • Selecting a podcast excerpt
  • Preparing a preview for social media

Detect the BPM of a Song

BPM stands for beats per minute and describes the tempo of a piece of music.

The RouteNote Convert BPM Detector analyses an uploaded audio file to estimate its tempo. It supports MP3, FLAC, WAV and OGG files of up to 200MB.

Knowing the BPM of a track can help DJs prepare sets, producers match samples, musicians practise at the correct speed and creators synchronise music with video.

Change the Pitch and Tempo

The Pitch and Tempo Changer lets you adjust the speed or pitch of a song.

It supports MP3, FLAC and WAV files of up to 200MB.

Changing a track’s tempo can help musicians practise difficult sections at a slower speed. Adjusting the pitch can make it easier to play or sing a song in a different key.

It can also be used creatively to produce slowed-down, sped-up or pitch-shifted versions of your own audio.

Add Reverb to Audio

Reverb creates the impression that a recording is playing inside a physical space.

A dry vocal recorded close to a microphone can sound more spacious after reverb is added. Instruments can also use reverb to create depth and help different parts of a mix feel connected.

The RouteNote Convert Reverb tool accepts MP3, FLAC and WAV files of up to 200MB.

Reverb can be useful for vocals, instruments, sound effects, podcast transitions and experimental audio. Applying too much can make a recording sound distant or unclear, so subtle adjustments often work best.

Adjust Audio Frequencies With an Equalizer

An equalizer changes the intensity of different frequency ranges within an audio file.

You might increase lower frequencies to add weight, reduce muddy frequencies or boost higher frequencies to improve clarity.

RouteNote Convert’s Equalizer works with MP3, FLAC and WAV files and supports uploads of up to 200MB.

Equalization can improve the tonal balance of a recording, although it cannot fully repair clipping, distortion or other problems captured in the original file.

Change the Volume of an Audio File

Some audio files are noticeably quieter or louder than others.

The Volume Changer lets you adjust the volume of MP3, FLAC and WAV recordings. It supports files of up to 200MB.

This can help when preparing voice recordings, music demos, podcast segments or other audio that needs a quick volume adjustment.

Be careful when increasing the volume of a recording. Pushing the level too far can introduce clipping and distortion.

Merge Multiple Audio Files

RouteNote Convert can combine several audio files into one continuous track.

The Merge Audio tool lets you order and merge up to five files of the same format. MP3, FLAC and WAV files are supported, with a maximum size of 200MB per uploaded file.

This can be useful for:

  • Combining podcast segments
  • Joining voice recordings
  • Creating a continuous DJ mix
  • Assembling chapters
  • Connecting several music demos
  • Merging sound effects

Convert Mono and Stereo Audio

RouteNote Convert includes tools for converting mono audio into stereo and stereo audio into mono.

Its Downmixer can also reduce the number of channels in a file, allowing users to select a mono or stereo output. The tool works with MP3, FLAC and WAV files of up to 200MB.

Mono audio can be useful for voice recordings, accessibility, compatibility and reducing file complexity. Stereo is generally preferred when the left and right channels contain important spatial information.

Generate a Waveform Image

A waveform is a visual representation of the amplitude of an audio recording over time.

RouteNote Convert can generate a waveform image from an MP3, FLAC, WAV or OGG file. Uploads of up to 200MB are supported.

Waveform images can be useful for podcast artwork, music promotion, video editing, educational material and social media content.

Create a Spectrogram

A spectrogram displays the frequencies contained within an audio file and how they change over time.

Unlike a standard waveform, which mainly represents amplitude, a spectrogram can help users visually inspect the frequency content of a recording.

The RouteNote Convert Spectrogram Image tool supports MP3, FLAC, WAV and OGG files of up to 200MB.

Spectrograms can be useful for analysing recordings, identifying background noise, examining sound effects and producing visual content based on audio.

More Free Online Audio Effects

RouteNote Convert also includes a wider collection of creative and practical audio effects, including:

  • Bass Booster
  • 3D Audio
  • Reverse Audio
  • Stereo Panner
  • Auto Panner
  • Low-Frequency Noise
  • Drunken Loudspeaker
  • Downmixer
  • Mono to Stereo
  • Stereo to Mono

There are currently 17 tools listed within the platform’s audio effects section.

Who Can Use RouteNote Convert?

The tools are designed to be accessible to beginners while still offering useful functionality for experienced creators.

They may be particularly useful for:

  • Independent musicians
  • Music producers
  • Podcasters
  • YouTubers
  • TikTok and Instagram creators
  • DJs
  • Students
  • Teachers
  • Video editors
  • Voice-over artists

You do not need to open a full audio production session every time you want to convert, trim or inspect a file. A focused online tool can often complete the job much faster.
