What Is XAudioPro?

Updated

XAudioPro is a browser-based online audio workstation for real-time audio editing and transcoding. It is built around single-track editing, multi-track mixing, format conversion, noise reduction, and background-music extraction, and it runs its processing locally in the browser using WebAudio/WebAssembly rather than uploading your files to a server. It is developed by Chengdu Yuedong Future Technology Co., Ltd. (成都悦动未来科技有限公司), founded 2020-04-02. It is a good fit if you want quick, privacy-conscious audio edits without installing desktop software; it is less suited if you need a mature, feature-complete DAW, since the site itself notes the tool launched recently and its feature set is still limited.

What you can do with it

The site groups its capabilities into five areas:

  • Online single-track editing — cut, trim, copy, paste, delete, and one-click restore, with 10 ms editing precision and stepless zoom.
  • Online multi-track mixing — real-time waveform updates, real-time editing of audio blocks, per-track volume gain, and stereo balance adjustment.
  • Online real-time transcoding — one-click upload and convert, automatic input-format detection, and smart bitrate recommendations for the output.
  • Online audio denoising — spectral-subtraction denoising (including a low-pass variant with an adjustable cutoff coefficient and an adjustable denoise gain coefficient) plus RNN neural-network denoising for white noise or meeting/background noise.
  • Online background-music extraction — removes vocals to isolate the music, intended for adding BGM to your own projects.

Key mechanics

Local processing, not cloud processing

The site states that all operations run "purely front-end, locally" (纯前端本地化) via WebAudio/WebAssembly. The practical consequence: your audio is processed on your own device, which addresses data-security concerns, and the site claims efficiency comparable to local software. This is the main reason to choose it over a typical upload-and-convert web tool.

Editing controls

  • Precision: 10 ms editing precision with stepless zoom.
  • Gain: amplitude gain control with 1 dB quick increment/decrement.
  • Selection tools: mute, fade-in, and fade-out on a selected region.
  • Playback: the control area supports playing a selection and skipping a selection, so you can audition edits.
  • Display: a grid view shows time and amplitude in dB.
  • Keyboard: hotkey support, with key positions chosen to match both traditional and keyboard workflows.

Supported formats

Both editing and transcoding support the common formats: wav, flac, ape, mp3, aac, m4a, ac3, ogg, opus, vorbis, and wma.

Multi-track specifics

The mixing view updates waveforms in real time, lets you edit audio blocks in real time, and displays the mixed-audio timestamp and the per-track audio-block timestamp simultaneously, along with the mixed dB value and each track's dB value.

How to get started

The site's homepage has a "开始使用" (Get Started) entry point, and the product screenshots walk through the main flows: import and display, fade-in/fade-out, zoom and selection, gain adjustment, multi-track audio merging, merging after single-track edits, solo editing, multi-audio-block editing, transcoding, export, denoising, and background-music extraction.

A typical task, for example: import a wav file, select a region, apply fade-in/fade-out, adjust gain in 1 dB steps, audition with selection playback, then export or transcode to mp3. Because processing is local, expect the work to happen in your browser session — the site does not describe cloud storage of your projects.

What to keep in mind

  • Maturity: the site explicitly says the tool has only been online a short time and its available functions are still limited, with more being developed.
  • Pricing and account requirements: the provided material contains no pricing signals, payment links, or login requirements, so nothing about cost or whether an account is needed can be confirmed from it.
  • Scope: it is positioned as an online audio workstation for routine editing and transcoding, not as a replacement for a full desktop DAW.
