- 1 Preface
-
- HDFrequency is a "Harddisk-recording-system" for Amiga® computers. Many HD
- recording systems do exist for amiga of course, but they all need
- external hardware (16 bit audio cards). So I decided to write a program
- that makes use of standard 8bit audio digitizers in combination with a
- harddiskrecording system. To my mind you can do lots of things with this
- program, and the quality is not so bad at all .....
-
- 1.1 Hardware requirements
-
- This program makes use of many features from Kickstart 2.0 .You should
- have at least Kickstart 37.175 to run this program. Lots of free space on
- your harddisk recommanded as well.
-
- There are existing 4 versions of the program:
-
- HDFrequency 68000 For amigas with at least 320 kB Chip & 450 kB other
- memory
- HDFrequency 68000e For amigas with 1MB Chip and at least 1 MB other
- ram.
- HDFrequency 68020 For amigas with 1MB Chip + 1MB Fast + 68020+.
- This version contains a 4 track CPU replayer.
- HDFrequency 68020l For amigas with 1MB Chip + 1MB Fast + 68020+.
- This version contains a 3 track CPU replayer.
-
- 68020+ versions of the program contain instead of a dma fourtrack that
- allows to replay 4 samples with 30 KHz at the same time, a cpu replay
- routine that allows replaying fourtracks with >30 KHz if your processor is
- fast enough. Fast means, that a 68030 25 MHz ist slow, a4000/040 would be a
- fine thing. For all those who do not own a4000/040, but an 68030, there is
- a version that only replays 3 cpu voices at the same time with sampling
- rates > 30 KHz.
- For all those who do not need sampling rates >30 KHz use the 68000
- versions, they allow replaying 4 voices with max 30 KHz at the same time,
- even on an old a500, 2mb.
-
- - Speed comparison of 68020+ versions
- (HD read = 600 kb/s, 58% cpu avail (a1200 At Bus)
-
- 4 Voices CPU 3 Voices CPU
- A1200 4 MB F 4 * 20 KHz 3* 28 KHz
-
- 68030 28 MHz 4 MB F 4 * 30 KHz 3* 36 KHz
- 2* 40 KHz
-
- 68030 40 MHz ???? ???? (Send me, if you can !)
-
- 68040 25 MHz ???? ????
-
- - 68000 Versions 4 DMA Voices
-
- A1200 4* 30 KHz
- A500 2MB Fast 4* 30 KHz
-
- Once again, if you only need sampling rates < 30 KHz, use 68000
- versions of the program package.
-
- Another point worth beeing noticed: The Speed of your HD, if possible use
- addbuffers XXX 1000, never use stacker® systems like xfh®, epu®,
- diskexpander®, they will slow down your hd quite a lot.
-
- 1.2 Contents

- hd_Frequency disk. This script uses the Commodore utility installer that
- should be available in the C: directory of your harddisk.
-
- Chapter II
-
- 2.1 The Audio Dock
-
- After calling the program from workbech you can watch a window with two VU
- meters, and on the right hand side of this window a small icon list. If
- this window is activated you are in the main control area of HDFrequency.
- All other program functions can be called from this window.
-
-
- 2.2 Project Menu
-
- 2.2.1 About
-
- This window gives closer information about the program and so on ..
-
-
- 2.2.2 Quit
-
- Here you can quit the program, what else ?
-
-
- 2.3 Sampler Menue
-
- This program supports standard sound samplers. In other sampling software
- you may find these so called standard samplers searching for 'generic
- samplers'. Perfect Sound® compatible samplers are not supported (yet).
-
-
- 2.3.1 Channel
-
- If you are using a stereo sound sampler you can decide using either the
- right or the left channel for recording samples.
-
-
- 2.4 Audio Menue
-
- 2.4.1 Replay Sample
-
- This routine replays a sample selected before. Position and time are
- displayed while replaying the sample. Replaying is controlled by using the
- icons on the audio dock window: <<, >>, stop and pause.
-
- You can start the replay routine also from the main dock window selecting
- the '>' icon.
-
- This routine uses DMA for replaying the sample. This means that samples
- recorded before with more than 30876 Hz are replayed with 30876 Hz, because
- normal amiga dma is not able replaying the samples faster.
-
- On 68020+ versions samples > 30876 will be replayed with the correct sample
- rate upto 62 kHz.
-
-
- 2.4.2 Replay Sample HQ
-
- This routine replays a sample, that was previously selected from sample
- editor. Now a CPU replay routine is used replaying a sample. The top
- sampling rate is now 65000 Hz (a1200+). DMA switched off and screen blanked
- to raise the quality of the sample. On a normal a500 the replay rate is
- round about 32000 Hz, because the processor is not fast enough. A sample of
- 30KHz replayed in HQ mode sounds rellay better than replayed in DMA mode.
-
- 2.4.3 Record Sample
-
- This function records a sample using the sample rate selected in 2.3.2. You
- can also enter this function by pressing the 'o' icon the the main window.
- Next you have to enter the filename of the sample to be recorded right now.
- Now you can control the input signal using the VU Meter and overpeak box.
- If the overpeak box look black the sample is overpeaked.
- After this, start the recording with the right mouse button or quit using
- the left one. To stop recording also press the left mouse button.
- If your processor is too slow for the sample rate you requested the program
- will let you know.
- Samples are recorded in standard IFF8SVX format. In this case you also can
- use iff-samples from other programs.
-
-
- 2.4.4 Playlist Editor
-
- Through calling this function you will enter the playlist editor. Within
- this option you can create 4 fourtrack tune.
-
-
- 2.4.5 Sample Editor
-
- After selecting this option you enter the sample window to manipulate samples.
-
-
- 2.4.6 Replay Fourtrack
-
- This function, you even may call this the main part of the program, replays
- a sequence created once before in the playlist editor. After picking this
- function a small window appears on the screen presenting you the current
- position of the playlist. With right mousebutton you can cue forward.
- Left mouse button aborts replaying.
-
- Some words about the 68020+ version:
-
- Holding down the Tab key before starting this routine will blank the screen
- and disable nearlly all DMA channels to improve quality.
- It is possible that the 68020+ routine is not able to replay the fourtrack
- correctly because your processor may not be fast enough. As an example it
- is not possible to replay two 40 KHz samples on a1200. In this case the
- interrupt routine will loop and loop and ...... press left mouse button to
- escape.
-
-
- 3 Sample Editor
-
- First select a sample to be edited using the asl file requester. After this
- you can watch the sample beeing displayed in a window. Using the size
- button of the window it is possible to change the size of the window.
- Using the mouse you can range a certain part of the sample to cut it off or
- something the like. Mark the sample by pressing the mouse botton somewhere
- on the sample window and releasing it somewhere else on the window. The
- intervall between the mouseclick will be displayed now, it is ranged.
-
-
- Here are some parts missing --> it's only a demo.
-
-
- 4 Playlist Editor
-
- Right in this part of the program you can create the sample lists required
- for the replay fourtrack routine. For each item of the viewlist you can
- choose its own channel and starting time, this is done by selecting the
- channel by clicking the mx_gadgets and to edit the time gadgets.
-
-
- 4.1 New
-
- Add a sample to the viewlist structure, choose your desired sample from
- asl_requester.
-
-
- 4.2 Delete
-
- A sample is deleted from the viewlist.
-
-
- 4.3 Get File
-
- Nearlly the same as 4.2. but here no new entry will be created, only the
- sample name will be changed.
-
- 4.4 Channels
-
- By clicking on the mx_gadgets you can select the replay channel for a
- selected sample from the viewlist. Default value is channel 1 after
- creating a new entry.
-
- 4.5 Time
-
- Enter the starting time of the sample and confirm by pressing return. The
- syntax is as follws 1.45'20'' = 14520
-
- 4.6 Start
-
- This one gives you the chance to change the start time of the playlist,
- this means that you can skip some samples. If the start time is 20000 all
- samples untill 2.00.00 are Skipped. Syntax is as in 4.5.
-
- 4.7 Project Menu
-
- 4.7.1 Load Playlist
-
- A playlist saved before with option 4.7.2 will be reloaded.
-
- 4.7.2 Save playlist
-
- A playlist created before can be saved to harddisk. Use asl_request to
- enter a name.
-
- III Other things
-
- 5 Technical information
-
- This programs makes use both of your processor and harddisk in quite an
- intense way. So be aware of using tools that reduce the performance of
- your processor such as stacker® systems like xfh® epu® (diskexpander®).
- If you are using epu or diskexpander use "epu device XXX chng nosave" to
- beware epu from crunching files while saving.
-
- Some things about speed: If you want to echo a 5 mb sample you need at
- least the following time
-
- 2 * Length of sample 2 * 5120 kb
- ---------------- ------------- = 14s ! (2 for reading
- Speed of Hd 750 kb*s^-1 & writing )
-
- Then you have to add the time the effect needs.
-
- The result is: The better hd and processor you have is, the better is the
- performance of the system.
-
- This version has been completely enforcer debugged.
-
- Program tested using
-
- a500 7.09 MHz 1 MB Chip 2 MB Fast 85 MB Quantum ELS Multi E.
- A1200 14.18 MHz 2 MB Chip 4 MB Fast 120 MB Connor IDE
- A1200/030 28.00 MHz 2 MB Chip 4 MB Fast 120 MB Connor IDE
- A4000/040 25.00 MHz 2 MB Chip 10 MB Fast 120 MB Quantum IDE
-
- Program tested using both kickstart 37.230 and 39.106.
- SetPatch 40.14 and 37.38 was installed on these machines.
