Why this analyzer is different
It checks more than the extension
The actual file structure is inspected instead of relying on the filename or extension alone.
快速 + deep analysis
You get structural properties first, then loudness, volume, and silence measurements useful for editing and publishing.
Large files are handled gracefully
The upload is designed to handle larger files reliably with clear progress feedback.

How the analyzer works
查看时长、编码器、采样率、声道、比特率和文件大小。
1. Fast local check
The browser detects the file, opens an audio preview, and calculates local signal metrics when decoding is practical.
2. Secure and reliable processing
The file is processed with clear progress feedback and automatic retry for temporary interruptions.
3. Audio results analysis
File, audio, and tag properties are extracted, then loudness, peak, silence, and quality metrics are calculated.
