Nine fixed SEEG readers had 2.4% mean error skill for 2–5 Hz sound changes on 100 later records at 400 ms delay
We compared fixed SEEG reading procedures for slow and fast sound amplitude changes. We used public SEEG data from OpenNeuro ds004703 version 1.1.0. The test used 100 later records from nine people and two fixed reading procedures. We did not fit new models. Each record had 117 targets at 10 Hz. An exact cosine transform split error into a constant term and two change bands. The slow band was below 2 Hz. The fast band was from 2 Hz to below 5 Hz. The 2 Hz boundary came from earlier work. At 400 ms delay, mean fast skill was 2.42%; at zero delay it was minus 12.01%. The mean paired change was 14.43 percentage points. Seven people had a positive change. The descriptive person bootstrap interval was 0.76 to 35.01 points. The exact sign-flip reference was 0.0898. Fast skill at 400 ms had an interval from minus 0.48% to 5.65%. Slow changes supplied 79.7% of the mean total error reduction. The planned sensitivity checks kept a positive mean fast change. Shared sounds, one large person effect, and different contacts at the two delays limit the interpretation. The result describes heard amplitude in the selected clinical recordings. It does not show general fast reading ability or a biological frequency limit. The SCI package preserves figures, code, source receipts, scores, and predictions. It omits source-derived feature and target caches because the external dataset terms conflict. Fresh public byte ranges reproduced all selected neural features and all sound targets in the local source study.

We used its cosine error method and 2 Hz boundary. The present readers and later records differ from its earlier test.

We used the fixed readers, selection of 100 later records, source range receipts, and clock checks. We measured their paired error change in sound frequency bands.
