Frequently Asked Questions
Privacy & Security
No. 360Converter Offline Transcriber processes all audio and video files locally on your computer. No data is ever uploaded to the cloud or shared with any third parties. Your files never leave your computer, ensuring complete privacy and security.
Yes. 360Converter Offline Transcriber is ideal for legal, medical, and other professionals handling sensitive information. Since all processing happens locally on your computer with no cloud uploads, your confidential recordings—depositions, client meetings, patient consultations—remain completely private and secure.
System Requirements
Windows:
- Windows 10 or 11
- 4GB RAM (8GB recommended)
- 2GHz dual-core processor or better
- 50GB free disk space
macOS:
- macOS 10.14 or newer
- 4GB RAM (8GB recommended)
- Intel or Apple Silicon processor
- 50GB free disk space
GPU acceleration is supported and recommended for faster processing but not required.
Yes, 360Converter Offline Transcriber fully supports Apple Silicon Macs including M1, M2, and M3 chips. We provide a native ARM64 build optimized for Apple Silicon, delivering excellent performance on these processors.
No, a GPU is not required. 360Converter Offline Transcriber works on CPU alone. However, GPU acceleration is supported and recommended for faster processing, especially with longer files.
Accuracy
Under ideal conditions (clear audio, minimal background noise), accuracy rates typically range from 90-98%. Accuracy depends on audio quality, background noise, accents, and terminology. The software includes a built-in editor for reviewing and correcting transcripts, and you can add custom dictionaries to improve accuracy for specialized terms.
Yes. 360Converter Offline Transcriber uses the same advanced AI speech recognition models as leading online services, achieving up to 95% accuracy. The main difference is privacy—your files stay on your computer instead of being uploaded to remote servers.
Transcription accuracy can be affected by:
- Poor audio quality
- Heavy background noise
- Multiple people talking at once
- Strong accents
- Specialized terminology
To improve results:
- Use clear audio recordings
- Enable speaker diarization for multi-speaker content
- Add custom words to the dictionary for technical terms
- Select the correct language model
Several ways to improve accuracy:
- Use clear audio: Good microphone placement, minimal background noise
- Add hotwords: Add names, technical terms, or jargon to the custom dictionary
- Use prompts: Provide context like "This is a legal deposition" or "Medical terminology expected"
- Select correct language: Ensure the right language model is selected
- Enable overlapped speech: If words are missing due to speakers talking simultaneously, enable "Contains overlapped speech" in the pre-configure transcription dialog
Advanced settings:
- Accuracy level: In Settings → General, choose from Standard, Medium, or Highest Accuracy. Higher accuracy requires longer processing time.
- Audio slicing: In Settings → Advanced, if you have enough memory, set Audio File Slice to 0 (no slicing). Default is 30 minutes. Note: Setting 0 with very large files and insufficient memory may crash the program.
- ASR Engine: In Settings → Advanced, switch from ASR Mode 2 to ASR Mode 1 for better accuracy. The accuracy level settings only apply to ASR Mode 1.
If some words are still incorrect after transcription, use Proofread or Free-Edit mode to correct errors manually.
Languages
360Converter Offline Transcriber supports 34 languages including English, Spanish, French, German, Italian, Portuguese, Chinese (Mandarin), Japanese, Korean, Russian, Arabic, Hindi, Dutch, Polish, Turkish, Swedish, Norwegian, Danish, Finnish, and more.
Additional language models can be downloaded from our language library. Go to Settings > Languages and click "Add Language" to download and install new language models.
Language access by license tier:
- Standard: 1 language included
- Premium: Purchase additional languages as needed
- Professional: All 34 languages included at no extra cost

- Transcribe & Translate: Transcribe audio/video directly to the target language or English in one step
- Translate after transcription: Click the Translate button in the left panel to translate your transcript into 32 additional languages using our AI
This makes it easy to transcribe foreign language content and get translations for multilingual teams or international audiences.
Features
Yes. 360Converter Offline Transcriber offers two microphone features:
- Record & Transcribe: Record audio from your microphone and transcribe it afterward
- Live Transcription: Convert speech to text in real-time as you speak
Both features work completely offline.
Yes. The Custom Dictionary feature lets you add specialized terms, proper names, technical jargon, and industry-specific vocabulary. This helps the AI recognize and correctly transcribe words it might otherwise miss or misspell.
Yes. 360Converter Offline Transcriber can transcribe any audio or video file, including Zoom recordings (MP4), Microsoft Teams recordings, Google Meet exports, and other meeting recordings. Simply open the file and start transcription. Speaker diarization can automatically identify different meeting participants.
Yes. The software supports common phone recording formats including M4A, MP3, WAV, and others. Speaker diarization can distinguish between callers. Since processing is local, your call recordings remain private and are never uploaded anywhere.
Yes. You can paste a YouTube URL directly into 360Converter Offline Transcriber. Note that this feature requires an internet connection to fetch the video, but the actual transcription still happens locally on your computer.
There is no built-in limit to file size or length with a licensed version. Files up to several hours can be processed on standard hardware. Very large files will require more processing time. The practical limit depends on your computer's specifications.
No. 360Converter Offline Transcriber automatically saves your edits while proofreading. If the app crashes or your computer shuts down unexpectedly, you'll be prompted to recover your unfinished work when you next launch the software.
Yes. Your transcription history is saved and accessible from the right panel. You can configure how many transcriptions to keep in Settings. This lets you revisit and export past transcripts without re-processing the original files.
Yes. 360Converter Offline Transcriber includes overlapped speech detection that can handle conversations where speakers talk simultaneously. This is particularly useful for:
- Group meetings and discussions
- Interviews with crosstalk
- Panel discussions and debates
- Casual conversations with interruptions
While most transcription tools struggle with overlapping speech, our AI is trained to separate and transcribe simultaneous speakers accurately.
There is no limitation — you can add as many files as you want. Multiple ways to add files:
- Select multiple files at once
- Add all audio/video files from an entire folder
You can configure each item individually if files are in different languages, or if you want to apply different hotwords or prompts to specific files.
Yes. You can configure batch processing to automatically export each transcript when done. Export settings include:
- Format: TXT, DOCX, or PDF
- Location: Choose your preferred export folder
- Auto-export: Enable or disable per batch
This lets you process multiple files overnight and have all transcripts ready in the morning.
A prompt is an instruction that guides how our engine transcribes your file. Use prompts to:
- Specify context (e.g., "This is a medical lecture")
- Indicate expected terminology or jargon
- Guide formatting preferences
- Improve accuracy for specialized content
Prompts are optional but can significantly improve accuracy for domain-specific recordings.
Yes. In the pre-configure transcription dialog, choose "Transcribe part of file", then specify the start time and end time in format: HH:MM:SS.
This is useful for long recordings where you only need a specific segment transcribed.
Performance
Hardware recommendations:
- Modern CPU (Intel i7 or i9 recommended)
- At least 4GB free RAM
- NVIDIA or AMD GPU
Software settings:
- Enable GPU: In Settings → General, ensure your GPU is selected. If "Don't use GPU" is chosen, transcription won't benefit from GPU acceleration.
- Speed level: In Settings → General, choose from Slow (Highest Accuracy), Medium, or Fastest (Standard Accuracy). Select Fastest for maximum speed.
- Disable overlapped speech: In the pre-configure transcription dialog, untick "Contains Overlapped Speech" — this processing takes extra time.
- Try ASR Mode 2: In Settings → Advanced, switch to ASR Mode 2. It may improve speed depending on your hardware — test on your own.
In Settings → General, select your best (highest-end) GPU from the dropdown and save. All subsequent transcriptions will use the GPU you selected.
In addition to the general speed settings (ASR Mode and Accuracy level), enable model caching:
- Go to Settings → Advanced
- Tick "Cache ASR Model"
This keeps the ASR model loaded in memory, allowing it to be quickly reused for each file in the batch instead of reloading it every time.
