How should I upload audio files?

All audio deliveries must be uploaded directly to Voicemachine. Do not deliver files to the client via email or cloud services.

File requirements:

• Upload 48 kHz, 24-bit or 16-bit, mono WAV or AIFF files (use 44.1 kHz only if requested by the client).

• Do not upload ZIP files—we process audio files directly.

• Maximum file size is 200 MB (split larger files if needed).

  
  

Editing guidelines:

• Basic editing is required unless the client requests otherwise.

• Deliver one edited file per take (remove mistakes and unwanted noise).

• Leave at least 1 second of silence at the beginning and/or end of each file to help our processing algorithms detect noise levels.

  
  

Naming and comments:

• Do not include notes in filenames—files will be automatically renamed (e.g., Take 1, Take 2).

• Add any comments in the comment field when uploading. These will be visible to the client.

  
  

Note:E-learning projects support custom file naming and splitting, which are included in those project types.
