![]() I would estimate at 20% of my collection hasnt been converted to a digital format by record labels… I would also say that collecting cheap albums for me is fun, and having them sound good for a small anount of money by the computer is part of my fun. ![]() You would be surprised at how many records have a digital preview in line when cutting and have been converted once already… ![]() ![]() You would also be surprised at how many people failed to hear the difference when an a/d/a convertor was thrown in-line and they didnt know it. You would be surprised at how many people will go on about playing analog purely and are running their signal through a receiver made since the 80s that have DSP and are already listening to something digitized and then converted back and never checked to see if their preamp/amp played things through a stritctly analog path. In parallel I will test the java software on my Mac. I am still struggling with the configuration of Pulseaudio and receive error messages but I will not give up on this (I am a linux beginner and it´s realy hard with Linux and Audio).Īgain - this is looking promising and let´s find out, if the raspberry can cope with this task.Īt this time I am not sure if the processing power will be enough. It´s an old piece of software and it needs java… I already spent some time to get the software ClickRepairRT installed and running on a Raspberry PI4. This software does not have a realtime click removal function So there is no “additional” time needed after the recording session which is fine. Maybe it started with analytics in parallel to the recording - I am not sure. and the result was very good - the clicks disappeared by 90%. Īfter I recorded to flac the process of “de-clicking” took a very short time - 2 minutes max. My “offline” click removal was done with the VinylStudio Software and an old late 2009 Imac. Many thanks for your comments, information and feedback. It will have some serious grunt compared to anything CPU based, be it x86, AMD64 or ARM. Taking that SweetVinyl example you’ve put forward, that money is going toward both the R&D cost of the algorithm but also the FPGA that’s likely to be at the heart of its processing capabilities. I know it certainly is the case for my PC, running Izotope RX7 with an i9 processor and that’s only marginally slower than realtime but still too slow to smoothly render during playback.ĭe-clicking needs to read ahead and process a fair chunk of data in order to be able to keep up with the audio it ends up playing out. I’m willing to bet it took longer to process than the file’s actual playback time. To get an idea, you mentioned that you processed a file offline and then played it back. You would need to take into consideration the processing power required for this, as it wouldn’t be something a Raspberry Pi will handle in real-time, especially if the algorithm is set to a greater sensitivity and for a higher quality rendering.
