Why Transcribe Audio Files?

Before we dive into the how-to, here's why you might want to transcribe audio files:

• Content creation: Repurpose recordings into blog posts, articles, or social media

• Translation: Generate transcripts that can be translated to reach global audiences

Step-by-Step: How to Transcribe an Audio File to Text

Step 1: Choose Your Source

Calybro lets you transcribe audio from three sources:

Upload File

• Upload MP3, WAV, M4A, or other audio formats from your computer
• Files up to 2 hours and 1GB are supported
• Best when you already have the file saved locally

Paste URL

• Copy a link from YouTube, Google Drive, podcast hosting, or other platforms
• Calybro processes the audio directly from the URL
• Best when your audio is hosted online

Record Live

• Record using your microphone in the browser
• Transcription starts automatically after recording
• Best for interviews, meetings, or voice memos

Step 4: Configure Settings (Optional but Recommended)

Before or during processing, you can optimize settings:

Language Selection

• If the audio is in a non-English language, specify it
• This improves accuracy significantly
• Calybro supports 150+ languages

Speaker Count

• If the audio has multiple speakers, specify the number
• Helps with speaker identification and labeling
• Improves accuracy for interviews or discussions

Custom Vocabulary

• Add names, technical terms, or brand names
• Especially useful for specialized content
• Improves accuracy for industry-specific terminology

Step 5: Wait for Processing

• Processing is faster than real-time
• A 10-minute audio file takes about 2-3 minutes
• A 60-minute file takes about 10-15 minutes
• You'll see progress indicators during processing

Tip: You can navigate away and come back—the transcript will be ready when processing completes.

Step 6: Review and Edit Your Transcript

Once processing completes:

1. Review the transcript: Check for accuracy
2. Edit if needed: Fix any errors, especially:
   • Proper nouns (names, places)
   • Technical terms
   • Numbers or dates
3. Edit speaker labels: If multiple speakers, assign names
4. Use the summary: Check the AI-generated summary for key points

4. Use summaries: Start with AI summaries to understand content quickly
