What Is Batch Audio Conversion?
Batch audio conversion lets you convert large numbers of audio files from one format to another in a single operation. SoundWorks supports all major audio formats — MP3, AAC, AC3, Opus, FLAC, WAV, OGG, and more — with full control over codec settings, bitrate, sample rate, and channel configuration.
Whether you need to prepare hundreds of tracks for distribution, normalize loudness across an album, or convert a library from one format to another, SoundWorks handles it without requiring manual file-by-file processing.
Why Use Batch Audio Conversion?
Process entire libraries at once. Select hundreds or thousands of audio files and convert them all in a single operation. No more dragging files one at a time into a converter.
Professional codec control. Set exact bitrate, sample rate, channel count, and codec parameters. Choose variable or constant bitrate encoding, set quality presets, or fine-tune every parameter manually.
Loudness normalization. Normalize loudness across your entire collection to a consistent level. Essential for podcast episodes, album mastering, and content that needs to meet broadcast standards.
Preserve quality. Convert between lossless formats (WAV, FLAC) without quality loss. When converting to lossy formats, choose the highest quality settings your use case allows.
Zero cost. No subscription, no per-file charges, no watermarks. Process unlimited files with no restrictions.
What You Can Do
Prepare music for distribution. Convert master WAV files to the specific formats and bitrates required by streaming platforms, CD pressing, or digital stores.
Normalize album loudness. Apply consistent loudness normalization across all tracks in an album or playlist. Meet LUFS targets for Spotify, Apple Music, YouTube, or broadcast standards.
Archive audio collections. Convert legacy formats to modern, space-efficient codecs. Migrate entire audio libraries from WAV to FLAC for lossless compression, or to AAC for mobile listening.
Podcast post-production. Batch-process podcast episodes to the correct format, bitrate, and loudness for your hosting platform. Consistent output settings across every episode.
Game and app audio. Convert sound effect libraries and music assets to the format required by your game engine or application. Process hundreds of assets in one operation.
Audio cleanup pipeline. Combine conversion with loudness normalization as part of a larger audio processing pipeline. Prepare raw recordings for further editing or distribution.
How It Works
Step 1: Add files. Drag and drop audio files or select entire folders. SoundWorks accepts all common audio formats and shows a queue of files ready for processing.
Step 2: Choose output format. Select the target format (MP3, AAC, FLAC, WAV, Opus, OGG, AC3, and more) and configure codec settings. Choose from presets or set custom parameters.
Step 3: Set processing options. Enable loudness normalization, choose target levels, and set any additional processing options. Configure output folder and file naming.
Step 4: Convert. Start the batch process. SoundWorks converts all files with a progress indicator showing completion status. Processing uses all available CPU cores for maximum speed.
Offline and Private
Audio files can contain unreleased music, client recordings, confidential voiceovers, or proprietary sound design. SoundWorks runs all conversion and processing locally on your hardware. Files are read from and written to your disk without any network activity.
There is no cloud upload, no usage tracking, and no limit on how many files you process. Your audio library stays under your control at all times.
Frequently Asked Questions
What audio formats are supported? SoundWorks supports MP3, AAC, AC3, Opus, FLAC, WAV, OGG, WMA, and more for both input and output. Nearly any audio format you encounter can be converted.
Can I convert video files to audio? Yes. SoundWorks can extract the audio track from video files (MP4, MKV, AVI, MOV, WebM) and save it as a standalone audio file in any supported format.
How does loudness normalization work? SoundWorks analyzes the loudness of each file and adjusts the gain to match your target level (in LUFS). This ensures consistent volume across all files without clipping.
Is the conversion lossless? Converting between lossless formats (WAV to FLAC or vice versa) preserves full quality. Converting from lossless to lossy formats (WAV to MP3) involves quality reduction inherent to the target codec.
How fast is batch conversion? Speed depends on file count, duration, and codec complexity. SoundWorks uses multi-threaded processing to maximize throughput. A typical album converts in seconds.
Can I set different output settings for different files? The batch converter applies the same settings to all files in a batch. For different output settings, run separate batch operations with different configurations.
