You just finished your audio production, you upload it to your favorite platform... and the system rejects it. This frustrating error message is one of the most common problems encountered by audio content creators.
Streaming and audio sharing platforms apply strict technical criteria to guarantee optimal playback quality for their users. File format, codec, bitrate, sample rate: each parameter can be the cause of rejection.
The good news? In 95% of cases, this problem can be solved in a few minutes with the right tools. This article explains how to identify the cause of rejection and fix your file to get it accepted.

Why do platforms reject audio files?
Audio platforms impose technical restrictions for several fundamental reasons. First, they must guarantee a consistent user experience across all devices and connections. A poorly encoded file can cause cuts, distortions, or playback problems. Second, storage and bandwidth optimization is crucial for platforms hosting millions of files.
Technical requirements by platform
YouTube accepts MP3, AAC, FLAC and WAV formats. Recommended bitrate is minimum 192 kbps for music, with sample rate of 44.1 kHz or 48 kHz. YouTube automatically converts all files to AAC for streaming. Spotify requires uncompressed WAV or FLAC files for artists (via distributors). Frequency must be 44.1 kHz with 16 or 24 bit depth.
The most common errors
Unsupported format: you send an OGG file to a platform that only accepts MP3 or WAV. The solution is simple: convert to an accepted format. Bitrate too low: an MP3 at 96 kbps will often be rejected because quality is insufficient. Re-encode at minimum 192 kbps. Incorrect sample rate: sending a 48 kHz file to a platform requiring 44.1 kHz causes.
How to diagnose the problem
Step 1: Read the error message carefully. Most platforms indicate the reason for rejection (format, size, duration, etc.). Step 2: Check your file properties. On Windows, right-click > Properties > Details. On Mac, use Finder > cmd+I. Note the format, bitrate and frequency. Step 3: Compare with platform requirements.
Summary table of accepted formats
YouTube: MP3, AAC, FLAC, WAV | 192+ kbps | 44.1/48 kHz | 128 GB limit. Spotify (distributor): WAV, FLAC | Uncompressed | 44.1 kHz, 16/24 bit | Varies by distributor. SoundCloud: MP3, FLAC, WAV, AAC, OGG | 128+ kbps | 44.1 kHz | 5 GB limit. Apple Podcasts: MP3, M4A | 64-256 kbps | 44.1 kHz | No strict limit.

Upload your rejected audio file to Convertly Audio and note its current characteristics.
Select the target format compatible with your platform (e.g.: MP3 320 kbps, 44.1 kHz for YouTube).
Start the conversion and download your corrected file, ready to be accepted.
Pro tips
- Create a 30-second test file to check compatibility before uploading your full production.
- Always keep a copy of the original file in maximum quality (WAV/FLAC) before any conversion.
- Platforms often re-compress files: upload in quality slightly above the minimum required.
Common mistakes to avoid
- ✗Converting directly from one compressed format to another (MP3 to AAC) instead of starting from source file. Solution: always use your original WAV or FLAC file.
- ✗Ignoring corrupted metadata that can cause rejections. Solution: re-export the file while clearing metadata.
- ✗Only changing the file extension without actual conversion. Solution: use a conversion tool like Convertly Audio.
- ✗Uploading a file too large for the connection and getting a corrupted file. Solution: verify integrity after upload.
- ✗Not checking new platform requirements that regularly evolve. Solution: consult their updated documentation.
- ✗Applying excessive compression to reduce size, degrading quality below acceptable threshold. Solution: find the right bitrate/size balance.
