Transcribe long Tentacle Track E recordings the lav audio, not the camera files.
Four hours of lavalier audio from a Tentacle Track E come back as text in about 8 minutes once you copy the WAV files off the recorder and upload them, each up to 10 hours or 5 GB. A first-time visitor gets the first 20 minutes free, and the 240 minutes fit the $6 pack of 500 minutes, leaving 260.
From the recorder to a paper edit
A body-worn recorder holds the closest copy of the voice you have, and the smallest.
Getting the files off
The Track E records to its own memory card, usually as WAV files that carry timecode. Copy them to a computer with the recorder connected or through a card reader, then drop each file here; the Tentacle app and your manual show the current transfer options for your firmware.
Sizes at each bit depth
A mono WAV at 48 kHz grows by about 518 MB an hour at 24-bit and about 691 MB at 32-bit float. Four hours at 32-bit float is near 2.8 GB, above the 2 GB a file may be before a pack, so it starts once a pack is on the account. A 16-bit copy of the same day is roughly 1.4 GB.
Timecode and timestamps
Transcript timestamps count from the start of each file, not from the timecode written into it. Note the file's start time from your editor or the recorder app; adding it to any timestamp lands you on the same moment in the synced picture.
From WAV to selects
Each file returns with a brief of the main points, chapters with timestamps, key quotes and the names, dates and numbers mentioned. The subject is named in the summary, quotes and chapters, so selects for a paper edit can be marked before anyone opens the timeline.
Lav audio elsewhere
Hours of clean body-worn audio still sit unread until someone types them up.

FAQ
Tentacle Track E audio, the practical questions.
How long do 4 hours of Track E audio take?
About 8 minutes in total, since an hour of audio takes around 2. Several files from the same day go up as separate jobs, each finishing in a few minutes.
What do a production's interviews cost?
A single 4-hour day uses 240 minutes of the $6 pack of 500. Twenty hours across a production come to 1,200 minutes, which fits the $12 pack of 2,000; sixty hours, 3,600 minutes, need the $24 pack of 5,000. A first visit adds 20 free minutes.
Can I upload a 32-bit float file?
Yes, as long as it is within 5 GB, and within 2 GB before your first pack. If a long file is over 2 GB and you want to try it first, export a 16-bit copy, which reads identically.
Should I join the files from one day?
Not unless you want one document. Each file gets its own transcript and clock, which usually suits a shoot where every file is a separate setup or interview.
Does the subject have to speak English?
No. Any of 99 languages is detected from the speech, and a subject who moves between two of them is transcribed on the main one.
Which formats come back from a Track E file, and who hears the audio?
Every WAV returns TXT, DOCX, SRT, VTT and JSON. Files are transcribed on our own servers and never used for training, and deleting one removes its transcript.
