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. Accepting any format would multiply infrastructure costs.
Finally, some restrictions are related to copyright and content protection issues. Platforms analyze files to detect protected content, and some formats make this analysis impossible.
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. Spotify refuses MP3 files as they have already undergone compression.
SoundCloud accepts MP3, FLAC, WAV, AIFF, AAC and OGG. Minimum bitrate is 128 kbps, but 256 kbps or more is recommended. Files exceeding 5 GB are rejected.
Apple Podcasts requires MP3 or M4A (AAC) files with bitrate between 64 kbps (mono voice) and 256 kbps (stereo music). Recommended frequency is 44.1 kHz.
TikTok and Instagram accept MP3 and AAC with limited durations (60s to 10min depending on format). Quality must be sufficient to survive re-compression.
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 rejection. Frequency conversion is necessary.
Corrupted file: an interrupted download or failed encoding creates a file the platform cannot read. Re-export from source.
Excessive file size: exceeding the size limit (often 500 MB to 5 GB) results in automatic rejection. Compress or split the file.
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. Check their official documentation or technical FAQ.
Step 4: Identify the gap. Is the problem the format, bitrate, frequency, size or duration?
If you cannot find the cause, try converting your file to the most universally accepted format (MP3 192-320 kbps, 44.1 kHz) and retry the upload.
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.
Bandcamp: MP3, FLAC, WAV, AIFF | 128+ kbps | 44.1 kHz | 291 MB limit.
Deezer (via distributor): FLAC, WAV | Uncompressed | 44.1 kHz | Varies.
TikTok/Instagram: MP3, AAC | 128+ kbps | 44.1 kHz | Duration limit 60s-10min.
Preventing future rejections
Create export presets for each platform. Once you know the exact parameters, save them for reuse.
Always keep your source file in maximum quality (WAV or FLAC 44.1 kHz, 24 bits). You can always create optimized versions for each destination.
Check specifications before starting your production. If you're targeting Spotify, work directly in 44.1 kHz/24 bits rather than having to convert later.
Use reliable tools for conversion. Convertly Audio guarantees files compliant with industry standards.

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.
