As previously stated, unfortunately it is not possible to filter and extract the ibus files solely in relation to bus routes because the data we hold is not provided in a route specific format and therefore would require the manual extraction and scrutiny of each file, of which there are several hundred,  to determine which ones are relevant for your request. As you are aware, the iBus announcements are recorded as fragments and therefore some announcements would not feature in full as the full  announcement  would just be made up of two or more fragments that have already been  recorded and so in order to provide you with the relevant recordings we  would have to provide you with all of them.

You previously mentioned that you do not want these audio files on a CD,  however, in accordance with section 21 of the FOI Act, we are not obliged  to supply you with a copy of the requested information as it is already  accessible to you elsewhere, albeit via CD download. In addition, we refer  you to section 11(4) of the FOI Act where it states “Subject to subsection  (1), a public authority may comply with a request by communicating  information by any means which are reasonable in the circumstances”. As  stated, there are several hundred files that are too large to be sent  electronically. If you do not wish to provide your address then we can  arrange for a copy to be made available for collection at our office in  St. James Park.

If you would like a CD sent to you then please provide me with your address, or alternatively if you wish to collect the CD please let me know when you are available to do so.

Yours sincerely,
