Re: Multiple SD cards with HiRes Board

Hello! Yes, we have made an 8 SD card daughterboard to the VS1005 Developer Board. The HiRes recorder for that board is under debugging at the moment. I expect we can release the board and software in late August. It contains 8 microSD connectors and our 4 Mbit SRAM IC VS23S040 for buffering. We hav...

Example source code for WAV PCM decoder DECWAV.DL3

Hello! So far our audio decoders, like MP3 and Ogg Vorbis have been all closed source. While this is necessary for us, it makes it difficult for third parties to create their own audio decoders because there really are no examples on how to do this. To help with the issue, we have created a simplifi...

Re: 24-bit wav issues vs1005 hiRes

Hello Rob! VS1005 audio drivers support 32-bit or 16-bit audio. There is no 24-bit option. If you want to record to a file that is 24 bits, then you need to set the audio drivers to 32-bit mode, then strip and rearrange the bytes to the little-endian format required by RIFF files. Below you will fin...

Re: ENCMP3 Driver not loading

Hello! I have found the reason and I have a recommended solution to your problem. Open up the VSOS 3.55 solution, then open the file transient.c. Find the following line: SymbolAdd("_encMAlignBitsToByte", (void *)1, (int)EncMAlignBitsToByte); Change it to the following (lower case 'e' changes to upp...

Re: ENCMP3 Driver not loading

Hello!

I can confirm your issue.

Heikkij gave you a solution, and you may use that to go around the issue for now, but unfortunately that solution will make the driver ROM-specific. I will try to get you a ROM-independent solution as quickly as possible.

Kind regards,

Re: Reverb / Echo Generator for VS1005

Hello! I prepared two examples to show the effect of the new First Reflection option "-r". I used the same "Heights" speech sample from the earlier version. First, there is an example with the pre-echo delay set to the minimum value, 2 ms. All parameters for Heights_4.mp3: First reflection: 2 ms Roo...

Re: Reverb / Echo Generator for VS1005

Hello! Here is an updated version of FTOREV.DL3, and completely new driver FTOREV23.DL3. The FTOREV.DL3 driver has a new option "-r", which tells, in milliseconds, the delay before the first reflection. By using larger values, it is possible to create effects that are like the back well of a long ha...

Reverb / Echo Generator for VS1005

Hello! It is with great pleasure that I presend you with an all-new filter for VS1005: The Reverb Generator. The Reverb Generator is capable of creating a room-like or hall-like echo effect, with lots of customisable parameters. I am not sure if the package can be compiled with a non-custom VSIDE en...
