Transcription: This is the very long mono IFF8SVX test sample. At the beginning of the sample, you should have heard one second of one kilohertz square wave. Because the length of this sample exceeds one megabyte, some playback software will need to treat the sample as a special case that is either double or triple buffered. At the end of this test, you should hear another one second of one kilohertz square wave. Here it comes!
