Total Audio Converter X is a server-side SDK that converts MP3, WAV, FLAC, OGG, OPUS, AAC, WMA, and 25+ other audio formats — without external codec packs or media frameworks on the server. It runs headless: no GUI, no dialogs, no popups. Total Audio Converter X ships with both a command-line binary and an ActiveX/COM interface, so it drops into ASP, PHP, .NET, Python, Ruby, Java, and any other COM-aware backend. The full list of supported audio formats:
The program supports ID3 Tags and CUE files. It converts audio tracks on the fly. It doesn't need an intermediary WAV file.
High converting speed and batch conversions result in a simple and boredom-free process. Besides all this, Total Audio Converter X will play all files of selected media types for you when everything is done. Try it for free (30 days trial period, no limitations) and find out that it is really worth its money.

"We process about 50,000 podcast uploads a week. Total Audio Converter X handles the normalization step in our pipeline: incoming WAV and FLAC from creators gets transcoded to 128 kbps MP3 for distribution and a 64 kbps mono variant for low-bandwidth playback. The flag set is small enough to memorize, the binary is fast (around 8x realtime on our hardware), and we have not had to update any codec dependencies in three years."
Akira N.
Senior Backend Developer at a podcast platform
"Our audiobook ingest pipeline takes raw narrator WAVs and produces both AAC for streaming and MP3 for download. Total Audio Converter X runs as a Windows service on the encoding box; we feed it batches via -list queue files. The -ca flag for stitching chapter files into one continuous track saves us from writing our own concatenation step. Stable and predictable across four years of production use."
Sara T.
DevOps Engineer at an audiobook publisher
"Stations upload mixed source material in everything from CD-quality WAV to ancient RealAudio archives. Total Audio Converter X handles the entire input matrix and gives us consistent MP3 output for the streaming infrastructure. The fact that it can rip audio CDs directly is a bonus we did not expect, and we use it for the legacy library digitization side of the product without needing a separate tool."
Yusuf E.
CTO at a media SaaS for radio stations
"Bundled Total Audio Converter X into our music-management product under the Royalty-Free License. The one-time per-project fee was a fraction of what FFmpeg-based commercial wrappers wanted. Our installer ships and registers the ActiveX, our app calls it directly, and end users see only our UI. The 32-bit ActiveX limitation cost us a couple of days of pipeline rework, but support was responsive when we asked about workarounds."
Linnea J.
Independent Software Vendor
"Solid for our voice-content normalization step. We take phone-quality recordings and downmix to 22 kHz mono MP3 before sending to ASR. Total Audio Converter X handles every edge case our customers throw at us, including some genuinely strange formats like APE and MPC. The CLI is stable and the output is bit-identical run to run, which is what we need for a deterministic pipeline."

Lead .NET Developer at a transcription service
Total Audio Converter X ships with AudioConverterX.exe, a console binary built for web servers, schedulers, and back-end audio pipelines — no GUI, no dialogs, no user interaction. The flag set mirrors the desktop AudioConverter.exe; for the full reference see the command-line documentation. The recipes below cover the cases SDK customers ask about most often.
The simplest call — one source, one destination, one target codec.
AudioConverterX.exe "C:\music\track.flac" "C:\out\track.mp3" -cMP3
Process every FLAC in a folder and drop the MP3s into a sibling output directory. Quotes matter when paths or masks contain spaces.
AudioConverterX.exe "C:\music\*.flac" "C:\out\" -cMP3
Swap the mask for *.wav, *.ogg, *.ape, etc. and the target with -cAAC, -cOGG, -cFLAC, -cWMA, -cMP4, -cMPC to mix any source/destination pair.
Music libraries are rarely flat. -Recurse walks subdirectories; -kfs recreates the same Artist/Album tree on the output side instead of dumping every track into one bucket.
AudioConverterX.exe "C:\music\*.flac" "C:\out\" -cMP3 -Recurse -kfs
Lossy targets need an explicit bitrate; resampling is useful when the destination device or stream expects a fixed rate (44.1 kHz for CD, 48 kHz for video, 22.05 kHz for voice).
AudioConverterX.exe "C:\music\*.wav" "C:\out\" -cMP3 -br 320 -sr 44100
Drop -br to 128 for podcast-grade audio, or push to 320 for archival-quality MP3.
Audiobooks, lectures, dictation, and IVR prompts don't need stereo. Forcing mono cuts the file in half and avoids phase issues on phone-grade playback.
AudioConverterX.exe "C:\lectures\*.wav" "C:\out\" -cMP3 -ch Mono -br 96 -sr 22050
Use -ch Stereo, -ch JointStereo, or -ch DualChannels for music targets.
WMA supports two encode modes: constant bitrate (predictable file size) and variable bitrate (predictable quality). For VBR, the -wq quality knob runs from 1 to 100.
AudioConverterX.exe "C:\music\*.flac" "C:\out\" -cWMA -wm VBR -wq 90
For CBR mode use -wm CBR -br 192 instead.
For audiobook chapters, DJ sets, or single-file album distribution, -ca stitches the source files into one output track in source order.
AudioConverterX.exe "C:\music\AcmeAlbum\*.wav" "C:\out\AcmeAlbum.mp3" -cMP3 -ca -br 256
Drive a CD ripper from a script: pick the drive letter, choose the destination format, let FreeDB fill in artist/album/track names, and apply a track-name template.
AudioConverterX.exe "C:\rips\" -c ripcd -cd F -df flac -freedb -ctt "<track:2>. <title>"
Swap -df flac for mp3, wav, ogg, aac, mpc, ape, or wma to rip straight into any supported format.
When a worker process writes a queue file and the converter consumes it, you don't want file paths baked into the command line. -list reads file masks one per line; -log redirects errors and progress to disk so an unattended run leaves a trail.
AudioConverterX.exe -list "C:\queues\encode.txt" "C:\out\" -cMP3 -br 192 -log "C:\logs\audioconv.log"
For storage migrations — for instance, replacing a WAV archive with FLAC at half the size — -do deletes each source file once its destination has been written successfully.
AudioConverterX.exe "C:\archive\*.wav" "C:\archive\" -cFLAC -Recurse -kfs -do
Run a small test batch first: -do is irreversible, and you want to be sure the output directory and target format are exactly what you expect before pointing it at a full library.
