Short: NEW and FAST CD-Sampling utility Author: Mario Kubek Uploader: Martin Schulze Type: disk/cdrom Architecture: m68k-amigaos QUICKSAMPLER is Copyright © 1996/1997 by Mario Kubek. All rights reserved! QUICKSAMPLER is Freeware! QUICKSAMPLER is a program for reading digital audio data (CDDA) out of CD-ROM drives, which are capable of sending digital audio data (16 Bit) over the SCSI bus. This data can be saved in a file to a disk. This version works with TOSHIBA drives. Kickstart 3.0 is required, but it should also work with Kickstart 2.xx (not tested). This is version 1.5! Features: QUICKSAMPLER V1.0 can/does... ...save CDDA data (whole songs or part of songs) to a file in a very FAST way. ...save the audio data in the fileformats: CDR, RAW, 8SVX ...convert the CDDA data to following samplerates: 44100 (44.1 kHz), 22050 (22.05 kHz), 14700 (14.70 kHz), 11025 (11.025 kHz) ...change the byte order (MSB [Motorola format] at first or LSB [Intel fromat] at first) when saving 16bit data. ...change the audio channels in the file: STEREO, CHANGE STEREO CHANNELSIDE (what you normally hear on the left speaker of the CD is the right channel in the file and what you hear on the right speaker is the left channel in the file), LEFT ON BOTH CHANNELS (what you can hear on the left channel on a CD is what you get on both channels in the file, the right one has no influence), RIGHT ON BOTH CHANNELS (what you hear on the right channel on a CD is what you get on both channels in the file, the left one has no influence), MONO (the left and the right channel are summed up and devided by 2), MONO_LEFT (you will get only the left channel in the output file), MONO_RIGHT (you will get only the right channel in the output file). ...offer you a good looking process bar. ...tell you using the GUI how many bytes will have the output file. ...check before writing to disk, if there is still enough place. Imagine you want to create a file, which is bigger than the available free space on the disk. Then QUICKSAMPLER creates the audio file, sets it's size, which is calculated with help of intern routines. During this process it can happen that the end of the disk is reached. In this case QUICKSAMPLER closes and deletes the file, because it does not make sense to write to a file, which wouldn't contain all the data you wanted to have in it. Some other programs do not check the free diskspace. They simply write the audio data to the file after they have created it. So it could happen that during the writing process (lets say 1 or 2 minutes later) the end of the disk is reached. What now? The user loses time and audio data, which should be in the file. ...not waste ram-memory. The allocated memory is determined using the WB-tooltype "BUFBLOCKS" or with the CLI-Argument "BUBLOCKS". BUFBLOCKS can be a number between 0 and 65. The smaller the number is, the smaller is the allocated memory and QUICKSAMPLER must read from the CD more often. The bigger the number is, the bigger is the allocated memory and QUICKSAMPLER must read from the CD less often. Default number is 32. There are 3 buffers that have to be allocated. The sizes of them are calculated with the formula (BUFBLOCKS*2352/a_number_between_1_and_17) or (BUFBLOCKS*2352*2) when data in RAW 16bit STEREO 44.1 kHz are changed (CHANNEL processing) and saved. Actually during the reading and writing process only 2 buffers are used. Which buffer is used depends on the fileformat of the output-file. ...offer you a fast reading and writing routine (also for STEREO 8SVX). It is not so compulsory to write such a routine as you might think of. This is version 1.5. It includes... ...a speed increased reading and writing routine. ...a check, in which a routine determines automatically if there is a CD in drive or even not (with the help of the timer.device). In the previous version this check was performed using IntuiMessages. But if your CD drive was not mounted, the program could not receive an IDCMP_DISKINSERTED or IDCMP_DISKREMOVED message. And if you have inserted or removed a CD, QUICKSAMPLER could not recognize this diskchange and the display was not updated with the data of another CD or it was not cleared if no CD was inserted. Because of that you had to quit and restart the program to make the diskchange visible. This problem is now fixed. Now every 2 seconds the program checks if there is a CD in drive or not. ...the default-"device"-name "squirrelscsi.device", because in the last version the predefined name "1230scsi.device" caused an error, which was the reason for the little fragment "ice", which appeared, when you wanted to switch to 14700 Hz with the help of the Cycle-Gadget "FREQ". Somehow MaxonC++ has put the last part of the string "1230scsi.device", which is "ice", into textfield of the "FREQ"-Gadget, which should show "14700". This is not a programming-mistake, but surely a compiler-bug, because with the now intern used string "squirrelscsi.device" this error did not appear any longer. This problem is now fixed. ...several intern improvements.
