Large File Processing
Complete guide for processing long and large audio files. Learn about limits, optimization strategies, cost management, and best practices for extensive transcriptions.
Limits and Specifications
Individual File
Up to 8 hours - Limit per single upload. Ideal for most cases.
Daily Processing
Up to 50 hours - Total per user per day. For intensive use.
Simultaneous Upload
10 files - Multiple files at the same time. For efficiency.
Processing Strategies
Strategy 1: Manual Splitting
Difficulty: Easy to Medium
Split the file using editing software.
Step by Step:
- Use Audacity (free) or similar software
- Split into segments of 1-2 hours
- Maintain 10-30 seconds of overlap
- Export with the same original quality
- Name sequentially (part1, part2...)
Advantages:
- Full control over splitting
- Can split at logical points
- Works with any format
- Allows pre-processing
Disadvantages:
- Requires additional software
- Time-consuming manual process
- Need to combine parts afterward
Strategy 2: Sequential Upload
Difficulty: Easy
Upload the complete file and split if necessary.
Step by Step:
- Try a direct upload first
- If it fails, check your connection
- Compress the file if possible
- Use off-peak hours
- Monitor upload progress
Advantages:
- Simpler if it works
- Less editing work
- Continuous transcription
- No loss of context
Disadvantages:
- May fail with a slow connection
- Higher bandwidth usage
- Risk of timeout
Strategy 3: Smart Compression
Difficulty: Medium
Reduce file size while maintaining adequate quality.
Step by Step:
- Convert to MP3 at 192kbps or higher
- Use mono if you do not need stereo
- Remove long silences if appropriate
- Normalize volume if needed
- Test quality before uploading
Advantages:
- Significantly reduces file size
- Faster upload
- Maintains quality for transcription
- Saves bandwidth and time
Disadvantages:
- May reduce audio quality
- Requires technical knowledge
- Does not always solve the problem
Optimization Tips
File Preparation
Choose an efficient format - MP3 at 320kbps offers excellent quality with reduced file size
Remove unnecessary parts - Cut musical introductions, long silences, or irrelevant sections
Normalize the audio - Adjusting volume to a consistent level improves efficiency
Upload and Connection
Use a wired connection - Ethernet is more stable than Wi-Fi for long uploads
Avoid peak hours - Uploads are faster during off-peak times
Do not close the browser during upload - Keep the tab open until the upload finishes completely.
Costs for Large Files
Remember: cost is based on audio duration, not file size.
- 1 hour of audio = 240 cycles (with AssemblyAI at 15 cycles/min)
- 2 hours = 480 cycles
- 4 hours = 960 cycles
- 8 hours = 1,920 cycles
