See before and after

Compare both waveforms, read integrated LUFS and listen to the processed preview before committing to the queue.

Build the workflow you need

Stack the actions in the order the audio needs, move them up or down, remove what you do not need and reuse the setup next time.

Make loudness consistent

Match perceived loudness with Streaming, Podcast or Broadcast presets, target integrated LUFS directly, or peak-normalize when level is what matters.

Clean the beginning and end

Trim silence, cut an exact amount from either end and add controlled fades without opening every file in an editor.

Keep control of metadata

Preserve source metadata when it belongs in the result, or remove it from every exported file with one output setting.

Know what happened

Follow progress file by file. A failed item is reported clearly, successful work remains intact and stopping the queue never damages an original.

Your originals stay untouched

Every result goes to a folder you choose. Existing files are never overwritten, and cancelled or failed work leaves no partial export behind.

Choose the result

Export WAV or AIFF at up to 96 kHz with 16, 24 or 32-bit PCM, or make a compact high-quality M4A at up to 48 kHz. Preserve source metadata when you need it, or remove it for a clean export.

Quick answers

Questions about PX7 Audio Batch

What is PX7 Audio Batch?
Drop in audio files, build a visual processing pipeline, compare the result and export the whole queue. Native, private and fast on macOS.
Where does PX7 Audio Batch do its work?
PX7 Audio Batch processes audio locally on your Mac.
How much does PX7 Audio Batch cost?
PX7 Audio Batch costs €15 once. It includes a seven-day trial, and one app-specific key can be used on up to seven Macs. There is no subscription.
Which Macs can run PX7 Audio Batch?
macOS 14 Sonoma or later, Apple silicon
How do I normalize multiple audio files on a Mac?
Add the files, set a loudness target, and export the queue — each file is measured and adjusted rather than simply made louder. PX7 Audio Batch uses integrated LUFS with EBU R128 / ITU-R BS.1770 gating.
Can I batch process a folder of audio files?
Yes. Drop in a folder, build the processing steps once, and every file runs through the same pipeline. WAV, AIFF, CAF, M4A, MP3, AAC and FLAC can go in; WAV, AIFF and M4A come out.
How do I remove silence from the start and end of many audio files?
Enable the trim step and the quiet lead-in and tail are removed from every file in the queue. This tidies the beginning and end of each file; it does not close gaps in the middle of a recording.
Can I apply the same fade to hundreds of audio files?
Yes — the pipeline is defined once and applied to the whole queue, so a fade set for one file is applied identically to every other file in the batch.
Can I build a reusable audio processing workflow?
Yes. The steps are arranged visually and kept, so the same chain can be reused on the next set of files instead of being rebuilt. Originals are left untouched and exports are atomic and collision-safe.
