What a built session costs

Most sessions are ready to download the moment you pay for them. If you want one built to a shape that is not on the shelf, that is an extra rather than the normal way through. Either way the price follows two things and nothing else: how long the session runs and whether video is included. The same session costs the same for everyone, and no price here depends on who is asking. Membership in the application is a separate thing and is set out at the end.

Ready now, or built to order

The programmes listed on the programmes page are rendered in advance and wait for you. You pay, and the files are there — no queue, no render, nothing to wait for. Several of them come with video prepared the same way.

Building your own is the extra. You set the length, the beat and the carrier within the bounds each programme declares, and the session is generated for you after payment. It costs three euro more than the same length off the shelf, and it is not instant, because it has to be made.

The preview on the programmes page is there to show what the choices are and what they sound and look like. It is not the product and it is not a sample of one particular file.

Ready-made: Rendered in advance, available immediately, and reviewed before it is listed. This is the normal way to buy.
Built to order — 3 EUR extra: Configured by you inside the bounds the programme declares, generated after payment, and delivered when the render finishes.

Two things set the price

Length is the first, because a longer session is more audio to render, measure and store. Whether video is included is the second, because a rendered visual is a separate piece of work with its own file.

Nothing else is priced. The carrier, the beat, the phase plan and the starting programme you build from cost the same whichever you choose, because none of them changes how much work the render is.

Length: Priced in bands rather than per minute, so a session of 31 minutes and one of 44 cost the same. The band you land in is shown before you pay.
Audio, or audio and video: Audio is delivered in three formats at no difference in price. Video is an addition with its own price, not a different edition of the same thing.

The length bands

These are the audio prices in euro. Value-added tax is settled at checkout against the country you are buying from, so the amount you pay may differ from the amount here.

10 to 24 minutes: 4 EUR
25 to 45 minutes: 7 EUR
46 to 60 minutes: 9 EUR

With video

A session with video costs double the audio-only price. The video is a second render rather than a different edition of the first, and it arrives alongside the three audio files rather than instead of them.

A video you download plays on a display nobody has measured, so it carries no calibrated visual dose and no full-field flashing. What it carries is what the preview shows: the plate and membrane figures, the spirals, and the oscilloscope, moving with the audio.

10 to 24 minutes: 8 EUR
25 to 45 minutes: 14 EUR
46 to 60 minutes: 18 EUR

One video quality, chosen on measurement

Video is delivered at 1920 by 1080, thirty frames a second, H.264 in an MP4 alongside the audio. One quality rather than a choice of several, because a choice you cannot judge before buying is not a useful one.

The figures below are why. They are measured on this material rather than taken from a general table: a rendered field of thin bright lines on black compresses unlike ordinary video. Four times the resolution costs eleven times the processing for a picture whose detail is a one-pixel line, and a session that took most of a day to produce would not be a session you could order.

1280 by 720, 30 fps: About 0.40 GB for an hour. Cheapest to produce, and visibly coarse on the thin nodal lines the figures are made of.
1920 by 1080, 30 fps — what is delivered: About 0.56 GB for an hour, and roughly forty minutes of processing to encode it. The figures rotate slowly enough that thirty frames a second carries them without judder.
1920 by 1080, 60 fps: About 0.92 GB and nearly double the processing, for motion that is already smooth at thirty.
3840 by 2160, 60 fps: About 1.81 GB and roughly seven hours of encoding for one hour of video. Not offered.

What arrives

Every audio purchase includes all three formats. They are the same render, encoded three ways, not three different masters.

WAV, 48 kHz, 24-bit: The master itself, uncompressed. About 1,037 MB for a 60-minute session. Its sample values round-trip to within one part in 8,388,607.
FLAC, 48 kHz, 24-bit: The same samples, losslessly compressed. Smaller than the WAV by an amount that depends on the content.
MP3, 320 kbit/s constant: About 144 MB for a 60-minute session. Measured at 78.71 dB against the master, where the same file at 128 kbit/s reaches 26.03 dB, and the difference between the two channels is preserved to four decimal places, which is the part a binaural session depends on.

Membership is a different thing entirely

Everything above buys one file. Membership buys use of the application, where sessions are generated and played rather than downloaded, and the two do not substitute for one another: a membership does not include downloads, and a download does not include the application.

These are the tiers the application carries today. Free is genuinely free and is not a trial that expires.

Free: No charge. Three sessions a week, up to 20 minutes each, seven days of history, no device integrations.
Premium — 9.99 EUR a month, or 99.99 a year: Unlimited sessions up to 60 minutes, three device integrations, ninety days of history, expert mode.
Pro — 19.99 EUR a month, or 199.99 a year: Unlimited sessions up to 120 minutes, unlimited device integrations, unlimited history, expert mode.
Enterprise: Contact us for pricing. What it covers is agreed case by case, so there is no listed figure to quote.

Nothing on this page is for sale yet

These are the prices a session will carry, not prices you can pay today. The purchase path is not open, and this page does not offer one.

Before it opens, each price needs an approved payment object behind it, a tested guest checkout, verified delivery of the exact file, a reviewed licence for what you may do with it, a settled tax treatment, and a recovery path for a purchase you lose access to. Publishing a price before those exist would be advertising something that cannot be bought.
