LPCM or MP3 · USB · 100 min in under 4

Transcribe long talks from a Sony PCM-A10 LPCM or MP3, as recorded.

A 100-minute talk recorded on a Sony PCM-A10 comes back as text in under 4 minutes, whether the recorder saved it as LPCM (a WAV file) or MP3. The first 20 minutes are free, and the $6 pack of 500 minutes holds five talks of that length.

Off the recorder

The PCM-A10 keeps files in its own memory or on a microSD card. Either way, the file uploads as it is.

Getting the file off

The PCM-A10 has built-in memory and a microSD slot. Plug the recorder into a computer by USB and it appears as a drive; the recordings sit in a folder on whichever storage you recorded to. Copy the file across, then drag it onto this page.

LPCM or MP3 for long talks

LPCM is uncompressed. At 24-bit, 48 kHz stereo it grows by about 1.04 GB an hour, so a 100-minute talk is around 1.73 GB, still under the 2 GB that uploads before a pack. A 128 kbps MP3 of the same talk is about 96 MB. The words come back the same from either.

The 100-minute arithmetic

100 minutes is the length we see most often among paid uploads, and it divides the smallest pack neatly. One talk uses 100 of the $6 pack's 500 minutes and leaves 400, which is four more talks. A sixth talk is when the $12 pack of 2,000 starts to make sense.

What a talk becomes

You get the speaker's thesis and takeaways in a brief, chapters with timestamps that follow the slides, and every name, number and date they said. The questions the talk answers are listed, and the chat tells you what was said in the Q&A without replaying it.

Long talks elsewhere

A good recorder captures the whole talk. Then the file meets an upload limit.

✗ The usual friction

Hi-res audio is heavy, and a long talk makes it heavier.

00:02:14 I want to start with a map, because the whole argument tonight depends on where the river used to run.

00:38:51 The council records from that decade show the bridge was approved twice and built once.

01:21:07 Was the second approval because the first design failed, or because the money ran out?

01:22:30 The money. The design was fine. It just cost twice what anyone had budgeted.

FAQ

Sony PCM-A10 recordings, the common questions.

How long does a 100-minute PCM-A10 talk take?

Under 4 minutes at about 2 minutes per audio hour. A full day of talks, six hours, takes about 12 minutes of processing in total.

What do 100 minutes cost?

On a first visit the opening 20 minutes cost nothing. The rest uses minutes from the $6 pack of 500, so one talk leaves 400 minutes, or four more talks of the same length. Credits do not expire.

LPCM or MP3: which should I record long talks in?

Either works for transcription. LPCM is the safer archive copy; MP3 keeps a whole day of talks to a few hundred megabytes. If the upload ever refuses a file, convert it to MP3 first.

The recorder split one talk into two files. What now?

Upload both and you get two transcripts, or join them in an audio editor and upload one file of up to 10 hours so the timestamps run on one clock.

Does the talk have to be in English?

Any of the 99 languages the service detects on its own. A talk given in Japanese, Hebrew or Spanish needs no setting, and a lecture that quotes another language is detected on its main one.

What can I download, and who has access to the audio?

Every talk exports to TXT, DOCX, SRT, VTT and JSON. Your recording stays with us alone: recordings are transcribed on our own servers and are never used for training, and you can delete any file.

Copy the talk off the A10. The first 20 minutes of the talk are free.
