DigitalHarvest publishes short, checkable notes for people who make music and short videos with AI tools and want to post them without avoidable technical mistakes. Each note answers one question and shows the command, file or measurement behind the answer. Posts are written in English; the Korean guides have moved to SmartAI Reviewer and are linked through the 한국어 글 모음 page.
Check audio before you post
- Before You Post an AI Song: Check Lyrics, Clipping, and the Ending — a listen-and-measure checklist for sung lyrics, true peak and the ending, from three of our own song files.
- FFmpeg Shows −1.5 dBTP. Did You Actually Fix the Audio? — why a loudnorm log line is not a measurement of your exported file.
- VoxCPM2 vs ElevenLabs for a 30-Second Science Short — one script voiced by a local open-source model and a paid service, timed and checked with Whisper.
Check video files before you upload
- Before You Upload an AI Song or Video: The Checks We Run — the free ffmpeg commands we run for loudness, silent gaps, frozen pictures and duplicate files.
- Same footage, different file: a duplicate-check test — why two files can show the same footage and still differ, and what a hash cannot tell you.
- Are these the same video? Free duplicate file checker — compares two files in your browser without uploading them.
Read the credit records with their dates
- Observed generation charges and spend the guard missed — the September 28 to October 4 window, including non-generation steps whose recorded balance did not change and requests that returned no job ID.
- October 13: a provider refusal before the plan switch, then an accepted request — a separate October 13 account record. The 08:53 provider failure and the accepted 10:49 request have different times and balance rows; the original estimated program label is distinguished from the article explanation.
Recording gear
- Buying Used or Refurbished Home-Studio Gear on eBay — what eBay's refurbished labels and Money Back Guarantee cover, and ten home-studio items with manufacturer facts only.
How to read these notes
We separate three things: what an official document says (linked), what we measured ourselves (with the tool and settings), and what is our opinion. A measurement on our files is an example, not a guarantee for yours. We do not promise views, approval by any platform, or income. If a post contains a referral link or links to something we sell, it says so at the top.

Read each measurement within its own stated account, file and observation window. A historical charge is not a current quotation, a successful job is not final publication, and an article link is not evidence of a customer order. Choose a note that matches the question you are trying to answer and use its stated limits when applying the result. The channel directory also separates English technical articles, Korean comparisons, travel buying checklists and children’s stories.
