Sending an incompatible audio file can have frustrating consequences: platform rejection, wasted time, or worse, a bad impression with a client or collaborator. Checking compatibility before sending is a crucial but often neglected step.
The technical parameters of an audio file – format, codec, bitrate, sample rate, number of channels – determine its compatibility with different destinations. A file perfect for SoundCloud may be unsuitable for radio broadcast or integration into a mobile application.
This article guides you through verification methods and teaches you how to anticipate compatibility issues before they occur, saving you valuable time.

What technical parameters to check?
File format (container): MP3, WAV, FLAC, AAC, OGG, AIFF, etc. Each platform or device has its supported formats. MP3 is the most universal, WAV the most compatible with professional software. Codec (encoding): sometimes format and codec differ. An .m4a file can contain AAC or ALAC. Check the actual codec, not just the extension.
Available verification tools
Convertly Audio: import your file and all technical characteristics are displayed automatically. It's the fastest and most complete way to check your files. MediaInfo (free, Windows/Mac/Linux): powerful desktop tool that analyzes in detail any type of media file. Displays codec, bitrate, frequency, duration and metadata.
Quick methods on each system
On Windows: right-click on the file > Properties > Details tab. You'll see duration, bitrate, and sometimes frequency. For more details, use MediaInfo or Convertly Audio. On macOS: select the file in Finder, then Cmd+I. Basic information appears. For complete analysis, open in QuickTime and check Window > Inspector.
Reading recipient specifications
Before sending a file, always consult the recipient's technical documentation. Platforms publish their requirements in their FAQs or help pages. For clients or collaborators, ask their technical preferences. A sound engineer will prefer 24-bit WAV, a web developer will want lightweight MP3.
Universal compatibility checklist
✅ Format: MP3 (maximum compatibility) or WAV (maximum quality) ✅ Bitrate: minimum 128 kbps, ideally 256-320 kbps for MP3 ✅ Frequency: 44.1 kHz (audio standard) or 48 kHz (video standard) ✅ Channels: stereo for music, mono acceptable for voice ✅ Bit depth: 16 bits (compatible everywhere) or 24 bits (production) ✅ Size: check recipient limit (often.

Import your file to Convertly Audio to automatically display all its technical parameters.
Compare the displayed characteristics with your destination requirements (platform, client, etc.).
If a parameter doesn't match, use the appropriate conversion tool and download the corrected file.
Pro tips
- Create a "template file" for each destination and visually compare parameters.
- Automate your checks with scripts if you process many files.
- Keep a rejection log to identify recurring errors.
Common mistakes to avoid
- ✗Relying only on file extension. Solution: check actual metadata with an analysis tool.
- ✗Forgetting to check duration on platforms with limits. Solution: note the limits of each destination.
- ✗Ignoring metadata (title, artist) that may be required. Solution: systematically fill in the fields.
- ✗Not testing playback before sending (undetected corrupted file). Solution: listen to at least the beginning and end.
- ✗Sending a 48 kHz file to a destination requiring 44.1 kHz. Solution: check frequency and convert if necessary.
- ✗Forgetting email attachment size limit (often 25 MB). Solution: use a transfer service or compress.
