Multi-track home recording for free

I’d like to interconnect my YouTube creations with this blog – so this time we’ll be talking about home recording with Audacity. It’s by no means Audacity tutorial – I just want to introduce Audacity and also demonstrate its limitations when you wanna enter the realm where acronyms like VST, MIDI and ASIO rule it all. I have also found out that it’s easier to talk English above beer than to produce the video in English language (don’t forget – I’m a Slovak :-) ). I grew fond of short cuts (or cross-fading cuts of my longer speech that wasn’t that good) and it is generally a lot of trying for me. And I expect the viewer to be a bit tolerant to my faults. I came to the conclusion that I should rather write a script before but I’m just way too lazy to do so. However… back to the Audacity.


WTF is multi-track recording? How to plug the microphone into the computer? Newbie warning! (If you know it all watch it only at your own risk or for fun. :-) )

First video is just the introduction to a very, very raw way how to get your sound into the computer via soundcard with 1/8″ jack (I meant 3.5 mm, but you know… imperial units are still often used in this world) – that is via typical microphone input available virtually on every computer. When you have a better microphone with XLR connector, you might end up with XLR on the other side of the cable or with 6.3 mm jack (1/4″). In any case you need a converter, jack-jack (in both size directions) are pretty common, XLR-jack is also possible but it’s another complication. Now imagine we have a (semi) serious microphone plugged into the computer (without preamp! It’s a Sin!) just to use my few bucks “Skype” microphone for the rest of the show and to introduce the Audacity.

With this setup I made my first songs – and of course the quality was poor. I’m still not too close to optimal home recording quality, but Audacity with microphone via soundcard is really rather just an emergency solution. However – it works, you can experiment and it does not cost you anything. Except the microphone and the computer of course. And whatever instrument you want to play. Later you find out that it’s not easy to record multiple tracks in sync (unless you’re really very lucky). That’s caused by so called latency. And latency is the core of the second video with Audacity as our main hero:


Audacity, latencies and ASIO. And when we’re talking about Steinberg also some VST is mentioned. In theory.

This time I added intro – it was made in REAPER. “Lead guitar” is actually played on MIDI keyboard and heavily edited later (read: corrected :-) ) and I also played a bit with the pan envelope (don’t worry, we might talk about it next time). The rest is mostly about latencies with some conclusion about Audacity in context of ASIO and VST usage. I don’t like the heavy sound of my computer you can hear all the time in the background, but you have to live with that until I buy some other microphone (probably some Koss headphones with microphone on it). I don’t wanna use dynamic microphone shown in the first episode because it’s not that handy. Maybe next time I’ll come up with better setup. Currently I’m not able to get playback from software into the captured video but maybe I’ll overcome it somehow later.

I have also next two videos uploaded already – they are just a short introduction into REAPER and I’ll cover them in some future post. I don’t want to continue in Reaper tutorial, but I wanted to introduce the DAW before I move on to hardware I use. The goal is to cover home recording on extremely tight budget (understand 500-1500 EUR or USD, choice is yours) so don’t expect miracles. But the time is right and it’s really easy now to have a reasonable home recording solution for the price of your choice. To add one more link, there is really awesome and extensive Guide to the Home and Project Studio by Tweak. Funny that I found it after I knew some of those answers (but far from even half of them). Sometimes it’s hard to find a guide when you actually don’t know what to search for. Isn’t it Ironic?

T500 minus, kudos to ZAR

This post is actually immediate continuation of my previous problem – it just took me some time to get to it. :-) After all my troubles with wannabe-freewares I got to the ZAR – or Zero Assumption Recovery software. While the software itself is not a freeware it has a free functionality. Luckily for me it was exactly that one I needed – image recovery from raw filesystem. I installed it on aforementioned Lenovo T500 I recently acquired at work and gave it a try. Many pictures were saved but not the ones I needed. Actually very old images were recovered. Than I discovered that whatever I do ZAR always reads only first 3.55 GB of the flash card. “Hm, wait, that’s strange!” One look to the Total Commander – right it reports 8GB card. I don’t know why I checked Windows format utility – but it wanted to format the drive only to 3.55 GB – so obviously ZAR wasn’t the only one “wrong” here.

Long story short. T500 card reader is either faulty or wrong drivers are installed or I don’t know what. I tried to reinstall drivers from Lenovo site, no luck – card was still only 3.55GB. I tried the card in my colleague’s T400 – it worked just fine! (I mean really worked as 8GB, not as it seemingly worked in my computer only to read garbage.) I couldn’t find help on Lenovo forums (yet, but after a few days the post is too low to anyone care) and I actually found out that many people have surprising amount of various problems with something I wanted for the quality. My T500 actually has also tricky fingerprint reader that sometimes gets stuck and reports “too short” swipe every two seconds or so and it’s close to impossible to enter the password. Not to mention very weak USB (I mean my wife’s Asus can power MIDI keyboard and USB audio interface better) – all three of them within 2-3 cm on one side. The computer is not THAT bad – it has actually pretty cool reviews (that affected me in my choice) – but I expected less problems for the money. Now I have notebook that looks solid (“you have a Thinkpad!”), has a nice display (1680×1050 in my case, love that) and… that’s about it. But I didn’t want to write about my disenchantment of the notebook initially.

I wanted to recommend you ZAR in case you need to recover your data from the filesystem! :-)

And my pictures? I inserted the card into the reader we have on Epson Stylus Photo RX585 and recovered every single image I thought was lost. In addition to this adventure (that ruined one half of my day and made my day afterwards) I found out how pictures are written on the card and that they use all the capacity even when I delete them every time I download them to the computer. I don’t know if it’s FAT feature (never knew about it), I doubt camera can manage it under the filesystem level – and I don’t care really. Important thing is that the card is used nicely considering limited number of write cycles. I know, I know – I wouldn’t reach the limit even if only the first portion of the card was overwritten again and again. I just like it as it is.

Freeware? No, scamware!

I have a bad day today. I pulled SDHC card out of my digital Canon and put it into my Lenovo T500 to move photos on the disk. MOVE. After that I found out that there are some files of various lengths with proper names. But none of them was proper JPEG file. Except one that contained three fourths of some old picture deleted long time ago. In a panic move – those are the worst ones – I copied files back to the card to check them in the camera. No luck. Now I don’t know if they were corrupted before. But my bet is that they had gone wrong somehow before this whole episode happened. I decided to recover any JPEG file on the media on a binary basis. JPEG has its typical header with magic number so maybe, just maybe I’ll find something.

I tried various recovery freeware programs that were simple or lame or whatever. And then I hit Smart Image Recovery – reportedly freeware download. Let’s try it, why not. Uh, the download wants my email to send me the download link (that should be the first warning, I know). Ok, why not, I rely on Gmail spam filter anyway. I downloaded the software and started it. Buy or continue free? What?! How could the word “BUY” find its way into the freeware? Of course I want to continue Free! Ok, paid functions will be disabled. Oh, man, paid functions? You mean you would show me the pictures and I would not be able to recover them, right? (In the end this crappy software found NOTHING on that card although some other free trial found many files – of course, recovery was not for free. :-) )

During the scan of the memory card dialog appears: You have some problems in Windows Registry and some temporary files (what a surprise!). Do you want to download our bla-bla cleaning software? You gotta be kidding!!! (I never use multiple exclamation marks, but I just felt like that in that very moment.) This is not freeware at all! I’ll run away if I see anything from Smart PC Solutions (or smartpctools.com) again. I don’t know what “scamware” really means, but it was the first word instead of freeware that came to my mind. Extremely annoying, not giving promised values and I feel safe only thanks to anti-virus solution I wouldn’t dare to turn off. Because you never know. This time it was only annoying software, but what it will be next time?
