What it does

This page answers one question: what DpdoAudioTools does, and where its limits are. The six points below are the full scope — each one maps to a real control in the app, and none of them is a promise the tool cannot keep.

  • Multi-format + DXD — Input FLAC / WAV / AIFF, output DSF / DFF / DST + DXD (WAV64/WAV/FLAC 32/24-bit) — one engine covering both DSD and PCM domains
  • Real-time DSD recording — PCM→DSD real-time conversion recording and native DSD capture (DoP / Native ALSA), with monitoring, headroom and duration control
  • High-order filtering — Kaiser / Remez / Blackman / Hamming / Hanning windows; CIFB modulator and MASH hybrid topologies
  • Batch mode — Multi-file batch conversion with per-track parameter overrides, CUE splitting and custom naming templates
  • Sound enhancement — Automatic panorama correction, harmonic saturation (tape/tube emulation), look-ahead limiter, psychoacoustic noise shaping
  • SACD authoring + DXD workflow — Pair with DpdoPackSACD to package DSF/DFF directly into SACD ISO or Dpdo DSD Disc; DXD mode outputs DAW-readable DXD files

FAQ

How do I get DpdoAudioTools?

DpdoAudioTools is part of the Dpdo product suite. Visit dpdo.cn for more information.

Which operating systems are supported?

Linux (x86-64) and Windows (x86-64). A macOS version is coming soon.

What hardware does the recording feature need?

An audio interface supporting ALSA or PortAudio. Native DSD recording requires a device supporting DSD_U32_BE via ALSA. DoP mode can transport DSD through any interface supporting 176.4kHz.

How compatible are DST compression and large files?

DST is compliant with the SACD ISO standard. The compression ratio depends on material complexity, typically reaching 50–60%. DST-compressed output in DFF format is supported. Recommended for archiving and SACD authoring.

How does it relate to the Dpdo conversion engine?

It is the graphical front end of that PCM→DSD conversion engine — same conversion core; the app handles file selection, parameters, progress and logs.
