It’s nice to see how smoothly the smart (micro)-blogging tool Posterous integrates with SoundCloud. If you’re on a SoundCloud track page (or any other page with SoundCloud tracks embedded for that matter) you can use the Posterous bookmarklet so post SoundCloud tracks on your blog in literally one click!

Here’s how it looks when you click the bookmarklet on a SoundCloud track page:

And then after clicking “Post” the track is immediately published on your blog:

Very slick, we like! Great for all you music bloggers out there!

We’ve just launched a small, but sometimes very useful feature on SoundCloud. It’s a new button on the edit-pages tracks that says “Replace this audio file”. Clicking it will bring up a file picker just like you would expect, so that you can upload a new version of a file you already uploaded. Very handy if you discover a glitch in the file you uploaded, or maybe you found that uncompressed version of a track you previously only uploaded in mp3 format.

The timed comments will stay at the same position as they did before, so keep this in mind and avoid uploading tracks with a different length. Replacing a track does not count as a file upload and won’t reduce your upload quota.

We’ve just added basic video support for SoundCloud. It’s quite simple: You can enter a link to a video in the edit screen for a track. You can of course enter any link, but if the link is either a link to Vimeo, Google Video, Youtube, or Viddler, we will display a button that will open a nice inline video player so that people can watch the video directly in the track page.

It’s really slick, especially if you upload HD video to Vimeo and buy yourself a Vimeo Plus account. Check out a video for one of my tracks, City Ports, for example.

With that, the SoundCloud teams wishes you all a nice weekend!

We’re really excited about the release of our brand new Cocoa/iPhone development kit, built by Ullrich and Gernot! This means you can really easily integrate SoundCloud in any Cocoa-based (iPhone 2.0+, Mac OS X 10.5+) application, complete with oAuth-based authentication, asynchronous requests and uploads with a progressbar. We have only begun to imagine what kind of cool audio sharing apps could be built using this little toolbox…

So if you’re an iPhone-hacker, don’t hesitate to download the source and start hacking!

We’ve also taken the opportunity to upgrade pretty much all of our API pages. We’ve moved all code and documentation over to Github, so it’s easier than ever to browse and fork it. Since long time there’s already a complete Python wrapper for our API, and now it’s been better documented as well.

We’ve just launched a new release of SoundCloud that we call Quentin, after that french guy who’s probably most known for this track:

Development of this new version has been going on for a while now, and it’s mostly been about behind-the-scenes stuff, like making the transcoding of audio files really fast even though we have thousands of files uploaded per day, making complex pages really snappy, and completing the upgrade of our servers.
The biggest and most visible changes to the site have already been live for a while (the multi-track uploader, gifts, and volume control), but there are also a number of smaller things that we’ve launched, like the pretty “I’m on SoundCloud” badges, and of course a bunch of bugfixes.

Now that we’re running on a much more scalable setup you can expect more significant feature updates coming in the next few weeks. We’ve got some mighty cool stuff cooking so stay tuned!

UPDATE: Our list of hot tracks is now back as well. Check it out!

In our last blog post we mentioned a few really cool ways that people were using SoundCloud and we’d like to tell you about another one. This time it’s all in the name of a good cause!

We know that many of you are on Twitter because we see you all busy using SoundCloud’s ’share via Twitter’ social feature that we launched last year. If you’re one of these people then you should definitely get involved in Twestival.fm (a sister-site to Twestival, the festival taking place in 184 cities worldwide on 12th February).

The organisers are asking artist, bands and labels to donate tracks via their SoundCloud Dropbox. These tracks will then be made available for streaming and download between the 5th and 19th February at the Twestival.fm website using a SoundCloud player. The site is hoping to raise $20,000 by asking visitors to leave a tip in a Radiohead ‘pay what you want’ style. All money raised will go directly to charity: water to help build five new drinking wells in places where many have no access to fresh water.

You can donate your track via the DropBox below or simply share a track you already have in the Cloud with http://soundcloud.com/twestival

Donate your track

We look forward to seeing how the campaign runs!
