Converting Amiga samples

[Examigan]

I forgot that I had a bunch of old Amiga samples saved from a long time ago. I may have asked about this years ago, but have forgotten if I even received an answer.

Is there an easy way to convert them all in Audacity (I also have HALion 6, not sure if it can convert them though) without having having the extra steps to use the Import Raw Data menu each time? It would be great to have it batch process many at once without doing that for each one separately.

Why would you even want those samples? They're 8-bit, and probably 22 KHz sample rate.

Nostalgia?

My bet is on sox.

(command-line only last time I realky looked)

what bert said. ( as usual )

googling will find an appropriate command line eg as in this

I had an Amiga 2000 back in the day. Part of it is nostalgia I guess, but I just like anything slightly crunchy/distorted sounding. I'm also a fan of the sounds from the Mellotron.

Thanks, I will check into that one.

I did exactly this some months ago in Audacity with a load of old Amiga files.

Import Audio -> <select file> - Signed 8-bit PCM, 11025 Hz -> Import

Sample rates might vary a little but most of them sounded fine with 11025.

I exported them all at 16-bit 11,025kHz, then became concerned that I might be losing some of the grittyness of the raw files when loading them into our fancy samplers. The listener would NOT be transported back to 1990, and the illusion would fail.

There were only around 200 samples, and although I must have attempted to batch process it, I do remember doing quite a few manually. Definitely worth spending the time on.. all those 4kB kicks and plucks.

I found this one site that mentioned a way that the Amiga could play 14-bit sound (way back when) if you had a 68020 or higher. I don't have an Amiga anymore, but I thought it was interesting that it was possible. I eventually bought a Toccata 16-bit card for the A2000, and never knew about this quality the Paula chip had until now.

"Amiga 1000, which was out in 1985 didn’t have the CPU power to be able to play raw wav files in 14 bit. But once you upgrade to a 68020 or higher, Play16 (can be found on Aminet as standalone and with GUI addons) is capable of playing raw wav files in 14-bit quality directly to your speakers that are connected to your Amiga."

Nice info, thanks.

When I wanted to convert old samples from my tracker times, I loaded them in in OpenMPT spread them across a span of notes, disabled antialiasing to get the nice crunchy tracker sound, and then rendered that file to wav (44.1kHz, 16bit in my case).

Thanks SeBear; looks cool, but Windows only.
