Lastly, go back into iTunes and update the Podcasts. Inside the Podcasts\cleaned folder, move the MP3s up a folder, then into their respective Podcast folders (overwriting the ones already in there). And then:Īfter the podcasts are done processing, switch back to the Explorer window. Now, in Audacity, go to File > Process Batch. Copy the fresh podcasts into the root podcast folder (for easier conversion). Then, navigate to the podcast folder in your iTunes Library. In Audacity, navigate to Edit > Preferences. Time: Configuring the batch script – 1 minute increasing the tempo of the podcasts – varies, depending on the number of podcasts being processedįirst, you have to configure the batch script.Except for the tempo increase, it won’t be automatic. So, if I want to speed up podcasts, I have to do some work. ( Effect > Change Tempo is the command you want.) There was a beta of the next version last time I checked that allowed bulk conversion. It is cross platform, open source (free), and up audio excellently, being a general purpose audio editor. Fortunately, Matt commented about Audacity:Īudacity is great for this, at an unbeatable price ($0). The article mentioned Amazing Slow Downer, but it’s not free. I have a 3G iPod, so I don’t have this feature. The feature is the ability to speed up (or slow down) audio without changing the pitch (if you are familiar with variable speed tape recorders, you understand that simply speeding up the playback of something tends to also make the speaker sound like a chipmunk). It’s the feature that Apple introduced with the 4G iPods back a couple of years ago. In other words, you get an extra 25% of content. It lets you play one minute and fifteen seconds of audio for every minute you listen. Here are the two sentences that caught my eye: ![]() Over a month ago, Lifehacker linked to an article: “ Speeding Up Podcasts and Audio Books“. Audacity 1.3.2 (Beta) changes the method a bit, which I describe here. On my iPhone/iPad I use the mobile version of ASD, also does the job quite nicely.Update : This post is outdated. wav format, but no big deal, I just export to. The only feature I wish they would add on the Windows version is direct export of. I'm sure there are other programs that would meet my requirements, but for desktop Mac and Windows systems, Transcribe! does all these things very well. Transcribe! is also able to slow down/pitch shift videos.Ī couple of demo videos I did showing the program in action doing these common tasks: I've been a user of Transcribe! for as long as they've been selling it, haven't found any reason to change to something else.ġ) Opening most common audio file formatsĢ) Ability to independently adjust pitch and speedģ) Ability to drop markers while the audio is playingĤ) Keyboard shortcuts to move between markers and select between markersĦ) External device control via MIDI (so I can use my Tranzport control surface) so I can run the app remotely from my practice chair instead of sitting at my computer deskħ) Ability to export both full files and selection regions with pitch and/or speed adjustments It doesn't help with the melody but if you are writing charts for a group to play it can be a time saver.īoth ASD and Transcribe! are useful for learning tunes. Band In A Box now has a feature which allows you to import audio and it very accurately maps the chord structure of the piece. There is another type of software that can be useful. One thing I like about TwelveKeys is that it has a treshold filter for polyphonic recordings which helps to isolate the lead instrument(s) playing the melody. Another package with similar features is TwelveKeys. It's grown up a bit since I last updated it but it works just fine for me. I'm using a rather old version of Transcribe. That's really helpful in doing transcriptions (doh!). It shows graphically what notes are being played at any particular moment in a recording and weighs each note played by how dominant it is in the mix. Transcribe is a different beast in my mind. I do find tempo and pitch shifting functions helpful in learning tunes by ear if the tuning is a bit off or the tempo is just too quick for me to pick up necessary details. ![]() If ASD has grown into something more since I used it, then please correct my aging view of things. I also used Slow Gold from Worls Wide Woodshed for a few years. ![]() Similar functions are built into popular media players like Windows Media Player and available as add-ons to Winamp, etc. I do not use it presently because there are so many other add-ons that do the same job. The Amazing Slow Downer is one of hundreds of programs that can allow you to change tempo and pitch. It's not clear to me exactly what you need to accomplish with this software but here's my view.
