Varun Gandhi's Speech Tape

There have been two contradictory news items today on the same question: whether Varun Gandhi's speech tape was doctored. The Hindu only quotes the report of the Forensic Science Laboratory and is emphatic that it was not. IBNLive also provides the other part of the story which is the result of the Chandigarh lab:

Sources in the Chandigarh laboratory say the voice in the CD matches Varun’s but it could have been edited to join sentences and make it look like one continuous speech by the Pilibhit MP .

So which one is it? And why did The Hindu not mention this at all?
