Multi-Provider Audio Transcriber

Extract and transcribe audio from video and audio files across cloud storage, social platforms, and direct media links. Paste a public URL, get a timestamped transcript with automatic language detection.

What You Can Transcribe

Paste one public URL per run from any of the sources below.

Video & audio platforms

• TikTok — public video links
• SoundCloud — public tracks and podcasts (single track URLs only, not /sets/ playlists)

Many other public video/audio URLs are attempted automatically when a link looks downloadable.

Cloud storage

• Google Drive, Dropbox, GitHub Raw, OneDrive / SharePoint, Box, iCloud Drive

Share links are converted to direct downloads automatically where needed.

Direct media & CDN links

Note: Only publicly accessible content is supported. Private, login-required, geo-blocked, or age-restricted media may fail.

Direct Media & CDN Links

Any direct file URL that returns the actual audio or video file over HTTP(S):

• CDN links (e.g. CloudFront, Akamai, custom CDNs)
• Signed or presigned URLs that point directly to .mp4, .mp3, .wav, etc.
• Public hosting URLs where the response is the media file (not an HTML page)

Examples:

{ "start_urls": "https://cdn.example.com/media/episode.mp3" }
{ "start_urls": "https://d111111abcdef8.cloudfront.net/video.mp4" }

Supported File Types

Video Files

• MP4, AVI, MOV, WMV, FLV, WebM, MKV, 3GP, and other common video formats
• Audio extraction: Automatically extracts audio track for transcription
• Optimized audio extraction: 16kHz mono output with 64k bitrate for minimal file size
• Format detection: Automatically detects video format and handles accordingly

Audio Files

• MP3, WAV, FLAC, M4A, AAC, OGG, WMA, AIFF, and other common audio formats
• Direct transcription: Transcribes audio files without conversion
• High-quality processing: Maintains original audio quality during transcription
• Format detection: Automatically identifies audio format and handles accordingly
• Longer duration support: Audio files are much smaller than video files, allowing transcription of longer content within the 3GB limit

Note: This tool intelligently processes both video and audio files. For videos, it extracts the audio track before transcription. For audio files, it transcribes directly for maximum efficiency.

💡 Audio vs Video: A 1-hour audio file (MP3) is typically 50-100MB, while a 1-hour video file can be 1-5GB. Use audio files for longer content to maximize transcription duration within the file size limit!

Use Cases

• Content Creators: Generate captions, repurpose content, and analyze performance.
• Marketers: Track brand mentions, analyze trends, and optimize strategy.
• Researchers: Study video and audio content and extract insights from public discourse.

• detected_language: BCP-47 code for the detected language (only for success)
• timestamp: Processing time

Usage

1. Provide a single URL – cloud storage, video platform, or direct media/CDN link
2. Ensure the file is publicly accessible
3. Check file size - maximum 3GB per file
4. Set appropriate Apify run memory - larger files require more memory (see Memory Requirements below)
5. Generate transcript with automatic language detection
6. Receive timestamped transcript in JSON format

Note: Only one URL can be processed per actor run. For multiple files, run the actor separately for each URL.

Memory Requirements

Important: Larger files require more memory allocation. Please adjust the Apify platform's run memory setting based on your file size:

• Small files (< 100MB): 128MB - 512MB memory is sufficient
• Medium files (100MB - 1GB): 512MB - 2GB memory recommended
• Large files (1GB - 2GB): 2GB - 4GB memory recommended
• Very large files (2GB - 3GB): 4GB - 8GB memory required

⚠️ Memory Warning: If you encounter memory errors or timeouts when processing larger files, increase the Apify run memory setting in the actor configuration. The actor supports up to 8GB of memory. Bigger files use proportionally more memory during download, audio extraction, and transcription.

💡 Pro Tip: Audio files are much smaller than video files! If you have long audio content to transcribe, consider using audio files (MP3, WAV, etc.) instead of video files. This allows you to transcribe much longer durations while staying within the 3GB file size limit.

Technical Details

• Unified Processing: Single interface handles all supported providers and file types
• Intelligent Detection: Automatically identifies cloud storage provider and file format
• Smart Link Conversion: Converts share links to direct download URLs for maximum compatibility
• Robust Download: Built-in retry logic and error handling for reliable file processing
• Optimized Processing:
  • Videos: Efficient audio extraction with minimal quality loss
  • Audio: Direct transcription without unnecessary conversion
• Quality Assurance: Automatic duration validation and file size limits
• Memory Management: Optimized for cloud environments with automatic cleanup
• Security: No persistent data storage - files are processed and immediately deleted

Memory Optimization Features

• Efficient Processing: Optimized for cloud environments with automatic cleanup
• Chunked downloads (8KB chunks) to minimize memory usage
• Automatic file cleanup after processing
• Garbage collection at key processing stages
• Memory monitoring throughout the process
• Optimized audio extraction with minimal quality loss
• Retry logic prevents memory waste from failed downloads

⚠️ Important: While the actor is optimized for memory efficiency, processing larger files (especially videos over 1GB) requires adequate memory allocation. Always increase the Apify run memory setting in the actor configuration when processing larger files to avoid out-of-memory errors. See the Memory Requirements section above for recommended memory allocations based on file size.
