Mono Mp3s at 160kbps?

Hi! I'm new to using Soundforge Pro 11. My apologies if this is a very simple question- I'm a newbie. I have to convert high quality .wav files (32 bit float) to mono mp3s at 160kbps. The highest choice in the custom menu for mp3s in SoundForge is 128kbps. The vendor I'm sending the files to specifically wants 160kbps mono files. How do I do it? Thank you in advance for answering this question! - Stephanie

SF Pro 11 should have a lot of kbs rate options. In the MP3 'Save as' window, select 'Custom' and uncheck the 'VBR' box which sets the encoder to Constant Bit rate (CBR) and select highest on the quality fader. Many more rates including 160kbs should now be available, up to 320kbs 48kHz. Is it's for video, choose 48kHz, otherwise 44.1kHz is standard.

Another option is rendering a PCM (.wav) and using a third-party encoder. For instance, WinLAME RC3, has many more options than the SF MP3 encoder including hi/lo pass filters among other parameters.

Thanks! I thought it was strange that when you go to Custom 160kbps isn't an option in SF 11 Pro. I tried everything to get that output and it would only give me 128kbps mono at 44.1k. I'll try to use the WinLAME RC3 and see if it gives me the right output. Thanks for answering! I also wrote to Magix to see why it isn't an option.

- It's always been that way with SF's Fraunhofer encoder., at least since SF-6 or 7 as I recall. Probably since the size of a mono file only needs to be half the size of a stereo to attain the same quality. e.g., A stereo file with roughly the quality as your mono 160kps fie would need to be encoded @ 320kps 160x2, If you can't find the RC3 version, I can send you a link and include my custom presets <.xml> file.
