Transcribe long multitrack sessions from a Tascam Portacapture X6 one mix in, one transcript out.
A 4-hour session recorded on a Tascam Portacapture X6 comes back as text in about 8 minutes when you upload one mix of it, and a single file may run to 10 hours or 5 GB. The first 20 minutes are free on a first visit and the 240 minutes use a $6 pack of 500, but a 32-bit float stereo file of that length is usually over 5 GB, so export a 16-bit or MP3 copy of the mix first.
From the X6 card to the page
Six tracks are for the mix engineer. The transcript needs one file that holds every voice.
Copying the take off
The X6 writes its takes to the memory card inside it, usually as WAV files grouped by take. Connect the recorder to a computer over USB or put the card in a reader, then find the take by its date and time. Check the recorder's settings if you are unsure whether a stereo mix was saved beside the separate tracks.
Why one mix, not six files
Each track uploaded on its own is charged for the full length of the session, so six tracks of four hours would cost 1,440 minutes for a single conversation. One mix costs 240 and keeps every question next to its answer in a running document. If no mix exists, combine the tracks in any audio editor and export that.
The 5 GB arithmetic
A 32-bit float stereo file at 48 kHz grows by roughly 1.38 GB an hour (48,000 samples × 4 bytes × 2 channels × 3,600 seconds), so four hours lands near 5.5 GB. Saved as 16-bit stereo the same mix is about 2.8 GB, which starts once a pack is on the account; as a 128 kbps MP3 it shrinks to about 230 MB.
Four multitrack hours, made readable
The session returns with a brief of its thesis and takeaways, chapters with timestamps that match the recorder's timeline, and the names, numbers and dates spoken into the microphones. The people on the panel are named in the summary, key quotes and chapters, and the chat finds the moment a topic was first raised.
Multitrack audio elsewhere
Float recording rescues the levels. It also makes files most transcription tools refuse.

FAQ
Tascam Portacapture X6 recordings, the common questions.
How long does a 4-hour X6 session take to transcribe?
About 8 minutes, since each hour of sound takes roughly 2. The bit depth of the file changes how long the upload takes, not how long the transcription takes.
What does one long session cost?
A first visit gets the opening 20 minutes free. The 240 minutes of a four-hour session come from the $6 pack of 500, leaving 260, and eight such sessions are 1,920 minutes, which fits the $12 pack of 2,000. Credits never expire.
Will a 32-bit float WAV from the X6 upload?
Yes, when it is under 5 GB and 10 hours, and under 2 GB before your first pack. Long float takes often pass 5 GB, so export the mix at 16-bit or as an MP3; the words come out the same, because float only protects loud and quiet peaks.
Should I upload every track?
No. Upload one mix. Separate tracks each cost the full session length, and each gives a document in which half the conversation is faint and far from its microphone.
Can a panel be in a language other than English?
Any of 99, detected automatically with nothing to choose. A panel that moves between English and another language is detected on its main language, and music between sessions is skipped.
What comes back, and where does the audio go?
TXT, DOCX, SRT, VTT and JSON, all from the one run. Every X6 session is transcribed on our own servers and is never used for training. Nothing connects to the recorder; you send the file yourself.
