Audiomaster IV got me many jobs in radio and other audio-related roles. Although I did not spread the disk, the disk was already spread to me... but I did spread the word. Cool Edit, Adobe Audition, all have roots in this awesome box of tools

@10MARC Ай бұрын

For sure! Cool Edit was great software back in the day. Heck if I could still buy a copy of Audiomaster I certainly would!

Interestingly enough, Paula cannot play back audio with a sample rate above around 30khz unless you are using a 31khz display mode or if you're using RTG like the pistorm you have to type in the 2 commands (the 2nd one will make the changes survive a reboot): SetEnv Picasso96/AmigaVideo 31kHz SetEnv EnvArc:Picasso96/AmigaVideo 31kHz If your audio software is using AHI, you can also find that when you apply the above setting, the sample rate slider for Paula audio can also be increased to 48kHz because normally the slider won't go up that far At least this is for 14 bit Paula modes. Not sure if the regular 8 bit mode requires this

Ah, I see. I will have to try that out. I do need to load AHI on this Amiga 500. I use it on most of my Amigas

Absolutely a very interesting review of the well known Amiga sampler. Watched the whole video. On my X5000, I use my BOYA mic connected to my phone, record with Voice Recorder, edit the samples in Audacity on PC stored on USB pen, then bring them for a final touch in OctaMED SoundStudio on the Amiga. Keep up the excellent work 🥰 ❤️ 🙏

It needs to receive input at Line Level only.

OK, so receiving input from something amplified like my phone or the computer screws it up then. Maybe some other digitizers properly filter our those signals and that's why they work OK with those sources?

@KarlHamilton Ай бұрын

@10MARC it should work with your phone etc but you'd need to turn the volume output level down to near it's lowest setting, which itself would give quality issues. The DAC in a phone just isn't designed for that.

Wow. I remember, earlier on, an audio digitizer that some university student designed. It was published somewhere, probably in an alternate Amiga publication. (You know that there were those, like Amiga Scientific). Anyway, I even corresponded with the designer. I gathered all the components, including case, etched my own circuit board, and then for some reason never got around to building the audio digitizer! Yes, I'm an idiot, but I was a busy guy.

@10MARC Ай бұрын

I remember hearing about the "build your own" audio digitizers. Looking at mine, they do appear to be pretty simple and straightforward devices. I should see if I can find an old article on a DYI unit.

@user-eg3li4hb9o Ай бұрын

Maybe the reason that works only with "real" rca outputs is because it wants a "line level" output (usualy 2.0Vrms). Headphone outputs have much higher power, because they are designed to drive headphones. You can try an adapter from a real cd player to a male 3.5 mm jack, and then with a female 3.5 mm back to the rca of the amiga. It should work fine. Anyway, great video as always! Keep up the good work!

@10MARC Ай бұрын

Thanks, I think that is exactly what the issue is. My other audio digitizer handles headphone output just fine, so I was surprised this one did not

Excellent review, and I can't hazard a guess as to where the problems with the adapter may lie. I have seen this on eBay and would have picked it up, but ended up going with a nice boxed GVP DSS8... :P Back in the day I had a Microdeal VideoMaster that slid on the side of the A500, and that could grab video as well as audio. It was limited but still worked quite well, and I wish I still had the recordings I did with it. I mainly used it to grab samples for songs I had made in OctaMED. Good times.

I have a sound sampler or two in storage back on the mainland but I have no idea when I'll ever have access to any of it again, so I think I might just buy a new sound sampler, as you pointed out they're handy when you wan to make your own games.

@-GrimEngineer-1337 Ай бұрын

It's all about impedance matching. It not the amplitude. RCA direct is meant for high-Z signals. Your sources were designed to drive headphones etc most likely as low as 8 ohms. The impedance mismatch is most likely your problem. Most of the time it doesn't cause a problem using a low-Z source to a high-Z load, but in your case it seems to be an issue. Most of the time the issue occurs with a high-Z source to a low-Z load. using the mixer changes the impedance to match.

@10MARC Ай бұрын

What a fantastic explanation. I really appreciate it! I guess I was just spoiled by my other audio digitizer working fine with those sources - but it is also a much more complicated digitizer.

@8BitRetroJournal Ай бұрын

So high impedance is usually a line-in/out signal, right? Btw, those Behringer mixers are also pre-amps. Wonder if Doug also bypassed it and hooked the rca out directly to the digitizer..

@TLang-el6sk Ай бұрын

My guess is that you have an impedance problem: 3,5mm connectors typically are used for headphones, there you have an impedance of around 32..200Ohm while a line input has around 60kOhm. So the output impedance of a line output is quite high (around 1..4kOhm) but needs to be low to drive a headphone. The specs e. g. in my cassette deck manual are quite incomplete but for headphones I found for example 3,3mW output power for a 32Ohm load. That leads to an output level of about 0,3V while line output is documented with 0,5V. So while the voltages do not differ too much my educated guess is that the digitizer interacts with the output impedance of the source and needs a certain impedance. You may want to try to put a resistor of 1..4kOhm between the output of the source and the input of the digitizer. I would be interested in the result...

@10MARC Ай бұрын

Since the problem seems to be solved by running it thru a mixer, I am just going to test the same sources running thru my halfway decent mixer and my cheap and cheerful $35 tiny mixer. I will probably do a follow up show

@FileFixer007 Ай бұрын

@TLang-el6sk He needs to lowering volume on phone. Every consumer audio equipment dont have hi input voltage. It is usaly somewhere between 150-350 mV (RMS). Standard for consumer audio equpment LINE IN is 0.447V or -10dBV max. Mobile phones have headphne output reference level at 0dBV or 1V on max volume or higher. Lovering volume somewhere between 30-40% of max volume level at mobile phone can be ideal to achieve -10 output level for line input at digitizer.

@jameslewis7620 Ай бұрын

The sample quality doesn't depend on the two pieces of software you used. On the Techno Sound software, you had the filter set to "On", reducing the clarity of the playback. It's a crude hardware low-pass filter on the motherboard. Switch it off and it will sound just as good :)

@10MARC Ай бұрын

I will have to check that. Sometimes the buttons become totally unresponsive. I can turn something on or off, or switch stereo to Mono and then suddenly the buttons just refuse to work again until I quit and relaunch the software.

I was disappointed with the quality of the samples I made using the bundled Technosound software, but got great recordings when using the sampler within ProTracker. MAYBE I happened to switch adaptors and it wasn't the software after all, I can't tell now. but I may go back and experiment again. PS I made music using stuff from my kitchen: kzfaq.info/get/bejne/p9iGoZan25rHhHk.html

@mikekopack6441 Ай бұрын

I'm thinking you're having a impedence issue. Or its a line level vs volume level issue. For example, a line out from something like say an old CD player is NOT the same as a headphone jack, even if they were both RCA jacks. Headphone jack is amplified, not raw signal.

@10MARC Ай бұрын

You are most likely 100% right. I guess some digitizers were tolerant of line level inputs and some were not. I know my Future sound on my A1000 has about 15 IC's on it compared to the two of this unit. That must be why my FutureSound works fine with amplified signals.

Arrrggghhhhh stop with the demon voice I'm drinking good beer (Dragon's Milk) ! 😀 I have a DSS8+ love that thing. Even now surprises people as to what I can do with on 30+ year old hardware. Did a thing about a year ago where I recorded some speech and said I would modify it. 15-20 mins later I did the usual cut the voice up and changed pitch ect and played that impressed but not that impressed. But as they walked away I played a quick DnB track I created (most of the time was spent doing that) using their voice totally, stopped them in their tracks mind blown (the track sucked BTW I'm no musician) I really need to get Imagine out and do an animation with a dinosaur singing to a track, I lost all my work years ago. lol

@@10MARC Back then (I still lived in the UK) I would say it was the Microdeal Megalosound that I saw the most, followed by the Technosound then the DSS. If memory is correct the DSS was a bit pricey. I have both a Meglosound and the DSS, with the DSS being a far better sampler. But the Meglosound does have it's uses with it's obviously more retro grungy sound (comparative to now, back then it was just all kinds of fantastic) which is why I still have it. My friend had the Technosound first and it was awesome.
