Audio Converter

Leggi in italiano

A tiny, no-frills audio converter for Windows. Drag your files in, pick a format, hit Convert. Built to turn a WhatsApp voice memo (.opus/.ogg) into a .wav in two clicks — and it handles 14 output formats besides.

It is a thin, friendly wrapper around FFmpeg: FFmpeg does the actual conversion, this just gives it a small window and a drag-and-drop launcher. Interface in English and Italian (auto-detected from Windows, switchable in the window).

Features

• Drag and drop files into the window, or drop them straight onto the launcher.
• 14 output formats: wav, wav24, mp3, flac, alac, m4a, aac, ogg, opus, wma, aiff, caf, ac3, amr.
• Reads almost anything on input, including the audio track of video files (mp4, mov, mkv, webm, avi…).
• Rename the output when converting a single file.
• Optional output folder (default: right next to the original — the source file is never touched).
• Batch: convert many files at once.
• Bilingual English / Italian interface.

Requirements

• Windows 10/11.

• FFmpeg on the system. The easiest way to install it:

  winget install Gyan.FFmpeg

  The converter finds FFmpeg automatically on the PATH, in the winget install location, or in a bin\ folder placed next to the scripts.

Usage

1. Graphical interface (recommended) — double-click Audio Converter.bat. Drag files into the list, choose the output format, optionally rename (single file) or pick an output folder, then press Convert. You can also drop files directly onto the .bat icon.

2. Quick to WAV — drop files onto Convert to WAV.bat; the .wav files appear next to the originals.

3. Command line (PowerShell):

   .\Converter.ps1 -Files "memo.opus" -Format wav
   .\Converter.ps1 -Files "a.opus","b.m4a" -Format mp3

Files

File	Purpose
Audio Converter.bat	Opens the graphical interface
Convert to WAV.bat	Drag-and-drop, quick conversion to WAV
Interface.ps1	The graphical interface
Converter.ps1	Command-line version
Engine.ps1	Shared logic (formats, strings, FFmpeg)

How it works

Engine.ps1 holds the format table (each entry maps to FFmpeg codec arguments) and the conversion routine; the GUI and the command-line tool both dot-source it, so there is a single source of truth. Output files are written next to the original (or to the chosen folder) with the same name and the new extension.
